Dialogues - How to Make a 2D Game in Java #15

[@RyiSnow]

*UPDATE* I recently updated the code so you can open the dialogue window by pressing ENTER alone (right now you need to press a directional key and enter key to open it). I've explained the process at the beginning of Part 23 video (at around a minute and half) so check if you're interested.

[@andrasfejes8988]

[@poecat8837]

I really like your way of explaining things. It's so organized and transparent; I've learned a lot. Thank you for your work and I'm looking forward to the next episode.

You're welcome and thank you for the encouraging comment!

[@UnderArea51]

Thank you for making these videos! My daughter and I are making her first retro game together. The game looks kinda like - in the ballpark of her Undertale PC game. She's been adding bits of code, making character move around on screen. We have long way to go LOL! I'll keep you posted.

[@RyiSnow]

Thank you for the follow-up! It's so refreshing to hear others' development story :) I hope you and your daughter will reach the goal!

[@nassergh4166]

thank you for the update!! can't wait to see the finished results!, your methods are creative and I learn a lot from these videos

I'm running into an issue when my player and npc are facing the same direction, they are getting stuck. If player collides with npc and both player and npc are facing left, instead of colliding, entities get stuck together. Otherwise all other collisions behave as intended. Basically, if I walk in to the back of an npc, or an npc walks into the back of me, both entities get stuck. Anyone else run in to this issue or know of any resolution?

[@matildebrandao6377]

Hey! I've just started watching ur tutorial on this and i have been loving it! An ideia, do you think you could teach us to make the dialogue and an image by it side with the character talking but in a more detailed way (pixel art ofc) like in Stardew Valley or Sea of Stars, that would be super cool! Anyways, loved ur content! :>

[@jamesconwell2767]

Loving the series, but cant wait to see what you think of next

[@smokeythebear1633]

For some reason I cannot break out of the dialog loop. When I press enter it just restarts the dialog tree again.

[@JJSugar2244]

Don't know if you've figured it out by now (I'm assuming you have) but for other people that might be having this issue, double check that you are resetting "enterPressed" back to false in the Player class, interactNPC() method.

[@clovercandii]

Hello, sorry for bothering! I was wondering if there is a way to be able to open the dialogue screen without pressing a movement key? because if i go over my object, stop moving and press enter, nothing will happen. but then if i click any movement key, even if i click it like 5 minutes later, the dialogue pops up then. it feels a little strange, but i'm not sure if there's a way to change that? thanks again for this in depth tutorial! it's been very fun following along and my project for my friend is looking very nice :)

[@RyiSnow]

> if i click any movement key, even if i click it like 5 minutes later, the dialogue pops up then. Hmm it seems I cannot reproduce this in my environment. The dialogue pops up only when you press the key in the direction of the NPC. If the window still pops up when you press any other keys as well, check your code. Maybe something is missing or wrong. If you want to open the window without pressing a movement key, add enterPressed == true to the key check if statement then you should be able to open the window by pressing enter alone.

[@clovercandii]

​@@RyiSnow Hello, thank you for replying to my comments! I just got time to try to implement your fixes, sorry for not confirming earlier. The first problem happened because I have a dialogue set to my chest, which has collision off. Implementing the fix to the second part (open the window without pressing a movement key) fixed the first one as well. Hopefully my understanding of " add enterPressed == true to the key check if statement" was correct- I added " || keyH.spacePressed == true" to the update method in my player class. public void update() { if (keyH.upPressed == true || keyH.downPressed == true || keyH.leftPressed == true || keyH.rightPressed == true || keyH.spacePressed == true) { } This worked perfectly except for some reason when I hold space it moves my character extremely slowly in the direction I was already facing for some reason. However, it's very very slight and pretty unnoticeable so I'm okay with it. Thanks again for replying to my comments, I really appreciate it!!

[@RyiSnow]

No worries and thanks for the follow-up! Yes, your spacePressed implementation is done correctly > when I hold space it moves my character extremely slowly Ah, that's because when you press space key, the program still add the player's speed value to player's worldX/worldY. This is indeed a bug. To fix this, Add: && gp.keyH.spacePressed == false to the collisionOn if statement. This way player's worldX/Y increases only when collision is false and space key is not being pressed. Then move this line: gp.keyH.spacePressed = false; to after the collisionOn if statement. Then it should fix the bug. Thanks for spotting this!

[@clovercandii]

​@@RyiSnow For some reason the reply I posted didn't post and I just noticed now. Thanks for answering! I tried your fix and it didn't work for some reason and I'm not sure why, so I did this instead: if (!collisionOn && keyH.spacePressed == false && (keyH.upPressed || keyH.downPressed || keyH.leftPressed || keyH.rightPressed)) { switch (direction) { case "up" -> worldY -= speed; case "down" -> worldY += speed; case "left" -> worldX -= speed; case "right" -> worldX += speed; } } and added this to the sprite if statements: if (keyH.upPressed || keyH.downPressed || keyH.leftPressed || keyH.rightPressed) { spriteCounter++; if(spriteCounter < 24) { spriteNum = 1; } if(spriteCounter > 24 && spriteCounter < 48) { spriteNum = 2; } if(spriteCounter > 48) { spriteCounter = 0; } } and that worked okay. does that work? is there anything that could be done simpler that i should do? Thank you!

Hi Ryi nice video but I have a problem, everytime I collide with the NPC from left or right we will both get stuck. this also happens with the door from the objects. It's just left and right, up and down is just fine any Idea how to fix this? also thank you for the best tutorial!

[@LeighFlies]

RyiSnow is this any good for the speak() method? I wanted to make it so it will pick a random dialogue every time but not repeat them until it's used them all, and to be flexible for different NPCs with different numbers of dialogues set. I only have one NPC in my game at the moment , and my main worry is that when I add another, they will end up sharing the same list which will screw it up, and I don't know how to refactor it to avoid that... I'm a beginner but it seems to work for now though and I wanted this feature, and in the future I want to add to this method by setting a flag if the dialogue is related to the game progression, which will override this stuff with actual important dialogues. For now though, what do you think? Really enjoying your course, thanks so much :) ArrayList usedDialogues = new ArrayList(); //this is defined at the top of the class to stop the second while condition always returning false... public void speak() { //GENERAL CHARACTER SPEAK BEHAVIOUR Random rand = new Random(); int dialogueCount = 0; for (int i = 0; i < dialogues.length; i++) { if (!(dialogues[i] == null)) { dialogueCount++; } } int randomValue = rand.nextInt(dialogues.length); //init only; while (dialogues[randomValue] == null || usedDialogues.contains(randomValue)) { randomValue = rand.nextInt(dialogueCount); if (usedDialogues.size() >= dialogueCount) { usedDialogues.clear(); // cycle round when used all dialogues } } gp.ui.currentDialogue = dialogues[randomValue]; usedDialogues.add(randomValue); switch (gp.player.direction) { case "up" -> direction = "down"; case "down" -> direction = "up"; case "left" -> direction = "right"; case "right" -> direction = "left"; } }

[@nickrogers5215]

Hi, I have some problems with my game Screen using vscode. Sometimes when I move the character around, there would be some black bars flashing on the screen. When I move horizontally, the black bars are vertical, and when I move vertically, the black bars are horizontal. I've had this problem ever since I was using the small map, but it was rare. Now, I get this problem way more using the bigger map. And also, when I run the code and then try to talk to the NPC for the first time, the code will take about 2-3 seconds before the dialogue box shows up. Afterwards, when I try to talk again, the box would show up immediately.

great tutorial. I have a suggestion that helped me alot. If you have a name id on your npc, say a string names old man, when you are in your loop to check for entity collisions, you can do a e.name_id comparison, add a boolean ad a counter just for debounce and it makes npc interactions alot easier. thank you!!

Hi, I am having a few issues with my npc. Sometimes both the player and the npc "blink" when they collide and one time they disappeared completely until I pressed a movement key. Also, the npc can walk through me and the top half of trees when approaching from the side, which is strange. do you know why that happens?

[@RyiSnow]

Oops, sorry I think that's because player's y and npc's y are equal so the draw methods didn't get called. Add an equal sign to one of those conditions (either way is fine) then the bug should disappear. I will update my post. Thanks for spotting this.

Cannot read field “ui” because this.gp is null, for me I didn’t add this.gp = gp to the NPC_OldMan class because of that it was giving me that error message. I figured it out and I’m happy to not delete the project and beat my head against the wall. I’m happy now!

[@dusklycanrocvlogs]

Hey RyiSnow! How can we make it so that instead of having the dialogue appear one line, then no dialogue and then pressing enter again for the next line of dialogue, we have just continuous dialogue until all lines of dialogue have been said and pressing enter to automatically cycle through each index of the dialogues array so that the dialogue box stays with each new line of dialogue instead of having it appear and then disappear and reappear again when enter is pressed?

[@RyiSnow]

It's a little complicated process so I can't really explain it in a comment. Since I've received similar questions from others as well, I will make a video about an advanced dialogue system that features a page-flipping mechanism.

hi, nice video i wonder if adding an individual character image on the dialogue box is possible? i cannot seem to find a way.. thank you

Great videos! I however am experiencing an issue. Whenever I attempt to speak to an NPC for the first time, the game draws an empty dialogue box. Then when I press (Enter) again, it pulls up the first line of dialogue in the dialogue box. Then if I press (Enter) again, it brings up the first dialog first, then the next dialogue and repeats this until it pulls up an empty box again then repeats the cycle.

Great video, as always! However, I did notice I have a slight issue. When I hit enter to speak with the NPC, it only goes into dialogue mode if I am either pressing a movement key when I hit it or right after I hit it (basically, I have to be moving to interact with him, and if I don't, it still interacts the next time I do move). I know this has something to do with my input system. It's a modified version of the system you provided in the comments of one of the extra videos, where an ArrayList is used.

[@prizepig]

Ugh. I dont know what I am doing wrong here... I have retyped this code 4x now and I get the same error when trying to open the dialog text: Exception in thread "Thread-0" java.lang.NullPointerException: Cannot invoke "entity.Entity.speak()" because "this.gp.npc[i]" is null This is the location that causes the error and if I comment this line out, the dialog opens just fine (no text of course) public void interactNPC(int i) { if (i != 999) { gp.gameState = gp.dialogueState; gp.npc[i].speak(); } } Is there any way you can post the source code to your google drive so I can check my code against yours without having to start the entire lesson over again?

[@RyiSnow]

You get NullPointerException error when the program cannot find the targeted object. In this case, it's saying this.gp.npc[i] is empty (null). You can use this information as a clue to track down the cause. Here's how to track it down: 1. Check what index is returning null Type: "System.out.println("npc index:" + i);", right before the line which returns the error. Like this: if (i != 999) { gp.gameState = gp.dialogueState; System.out.println("npc index:" + i); // insert here gp.npc[i].speak(); } Run the program and reproduce the error. You'll get the index on the console. Probably multiple lines and the last one is causing the error. If you've only placed 1 NPC (in index 0), then I think it returns 1 or a higher index. This means the program is trying to read an empty object in the array and saying "I can't read this because it is empty". My guess is, that something is wrong with the checkEntity method in the CollisionChecker. 2. Check the checkEntity method Check the target scanning loop and make sure it is constructed not to read a null object. Like this: for(int i = 0; i < target.length; i++) { if(target[i] != null) { // Check if you have this condition. This prevents it to read null objects // Get entity's solid area position entity.solidArea.x = entity.worldX + entity.solidArea.x; entity.solidArea.y = entity.worldY + entity.solidArea.y; etc, etc... } } If you still couldn't fix it after doing these steps, let me know again!

[@prizepig]

​@@RyiSnow Wow, i didnt expect such a personalized response. I just made another attempt starting at the beginning of this video and again I am able to get up to the point where I add the dialogue text and i get the NullPointerException again. I added the System.out.println("npc index:" + i); to the Player class interactNPC(int i) method and it returns 'npc index:1' but then immediately fails on the gp.npc[i].speak() part. If I comment out that line of code the dialog box comes up with no text but no error either. I also checked the CollisionChecker class checkEntity(Entity entity, Entity[] target) method and it does have the correct IF statement 'if (target[i] != null). I'm not sure what else to try. I dont know why my npc[i] is 1 but the old man is npc[0]. Any further troubleshooting/guidance you can offer is greatly appreciated.

[@prizepig]

Also, i just tried to add i=0 to the interactNPC() method and the dialog works fine. So it seems like my npc[i] being set to 1 is the problem but I dont know why it's being set to 1. this is obviously not usable but it helps narrow down the issue. public void interactNPC(int i) { if (i != 999) { gp.gameState = gp.diaglogState; System.out.println("npc index:" + i); i = 0; gp.npc[i].speak(); } }

[@RyiSnow]

You can also try inserting the following three lines to narrow down the scope: for(int i = 0; i < target.length; i++) { System.out.println("current index in the loop:" + i); // Insert here if(target[i] != null) { System.out.println("currently checking index:" + i); // Insert here // Get entity's solid area position entity.solidArea.x = entity.worldX + entity.solidArea.x; entity.solidArea.y = entity.worldY + entity.solidArea.y; etc, etc... } } System.out.println("returning index:" + index); // Insert here return index; Apparently, the checkEntity method is returning [1] to the interactNPC method and there should be a reason for that.

You're great:) Also, I can interact with the NPC only only while pressing another button like w,a,s,d alongside enter. Is this how it is supposed to be?

[@RyiSnow]

Can't say for sure without seeing your code but if the texts are indeed processed and drawn in the program, likely cause would be: 1. Some objects are rendered after the texts and hide them. Check if ui.draw(g2) is being called after all other objects. 2. g2 was somehow disposed before rendering UI text. 3. If you have tweaked Graphics2D's alpha, check if you have reset the value correctly. About the key combination for opening dialogue window, I fixed it in Part 23 so you can start conversation by pressing Enter alone.

[@ganbarimasu9446]

@@RyiSnow how do I do the third step you've typed above. By the way, I can see the draw time on the screen but cannot see pause text, opening screen or dialogue screen. The difference I can see is drawTime is a part of play State while the others are from different states. I've watched your previous videos many times and compared to my code but they seem the same. I am stuck and cannot continue to this series so I am sad :( note: I can paste my code if necessary. note2: I just tries I can control title screen and even close the game using keys. So the problem isn't exactly a coding mistake, but a problem with printing on screen. I checked whether it is being written in the background because pf the priority of the upper code lines but couldn't see anything..

[@RyiSnow]

Try commenting out tileM.draw, obj.draw, npc.draw and player.draw. Start the game and check if you can see the title text or Pause text. When things like this happen, try bypassing/disabling the functions one by one and make the code as barebone as possible. If the issue stops, try reclaiming the disabled functions one by one while checking if the code runs correctly every time you reclaim a new function or lines of code. Eventually you reach the point when the issue starts and that's where you can find the cause. You're struggling to find it out because a lot of elements have been implemented into the code and makes it harder to track. But if you do this kind of back tracking, finding the problem is often not so difficult. Also, don't worry about the alpha if you have no idea what that is. It's something I introduced in later videos.

But basically you need something like this to change dialogues by pressing a key (I used Enter in this example): [KeyHandler] else if(gp.gameState == gp.dialogueState) { if(code == KeyEvent.VK_ENTER) { //gp.gameState = gp.playState; // remove this enterPressed = true; // add this } } [GamePanel / update] // add this if(gameState == dialogueState) { player.update(); } [Player / interactNPC] if(i != 999) { if(gp.keyH.enterPressed == true) { if(gp.gameState == gp.playState) { gp.gameState = gp.dialogueState; gp.npc[i].speak(); } else if(gp.gameState == gp.dialogueState) { if(gp.npc[i].dialogues[gp.npc[i].dialogueIndex] != null) { gp.npc[i].speak(); } else { gp.npc[i].dialogueIndex = 0; gp.gameState = gp.playState; } } } } gp.keyH.enterPressed = false; [Entity / speak] // remove this //if(dialogues[dialogueIndex] == null) { // dialogueIndex = 0; //} It's a pretty rough sketch but this way, the dialogue changes every time you press enter key and if the npc has no more dialogue, the dialogue window closes.

@@RyiSnow I tried this and it only works if the player is holding down a key(like "A") , walking into the npc and not letting go, if I let go for example "A" in the dialogue, it freezes and I cant press enter to continue the dialogue. any advice? edit: I just realized that anytime a dialogue is happening, if I let go of a movement key, for example "A" everything just freezes, and I have to quit the game, if that makes things clearer. edit2: btw, I can still move in a certain direction while talking to the npc. For example, if I walk left into the npc, start talking and not letting go of "A", the player still moves, but when I release "A", I can't walk anymore(still in dialogue). I don't know if this helps, but any help is very appreciated. Also thanks for the tutorials, I love them

@@carl4839 i have the same problem as you, have you fixed it?

@@MasonJarFilm Nah. Gave up on that project a while ago. Sorry.

I made a very simple change to our speak method as I really like the feel of the NPC essentially telling me to go away by just repeating their last line instead of cycling through previous dialogues. I'm a complete noob and I was very proud of myself. There is probably a better way, but this works for anyone who is interested. public void speak() { if(dialogues[dialogueIndex] != null) { gp.ui.currentDialogue = dialogues[dialogueIndex]; dialogueIndex++; } else { gp.ui.currentDialogue = dialogues[dialogueIndex-1]; }
