Unity 2D Platformer for Complete Beginners - #9 TRAPS

In this episode we'll create 4 types of traps: simple spikes, firetraps with pressure plates, arrow traps and a spiked block similar to the crush block from Spelunky.

When my fire trap activates it doesn't hurt me, not until i leave the collision area and return to it. In the video when you test your fire trap you jump out of the collision area and then back into it and get hurt so I can't tell if this is how it's meant to be or if I have messed up. If this is how it is meant to be could you possibly tell me how to have it so it hurts the player if they wait within the collision area. Thanks in advance if you find the time to help me out

[@PandemoniumGameDev]

You're right, I changed the script and now it's working properly: pastebin.com/APa4q1H1 I'll pin your comment, hopefully more people see it.

[@syris78]

@@PandemoniumGameDev Thankyou! It now functions as intended! well, almost.. it hits the character more than once as if its not pulling the command at set intervals using the delay but more like it's trying as much as it can to activate when the player is colliding. Any idea why this might be? Thanks again

[@PandemoniumGameDev]

@@syris78 It his the player once you enter then immediately after the invulnerability effect wears off, I think this is normal but you can increase the IFrames duration to avoid this or decrease the time the firetrap stays active.

[@syris78]

@@PandemoniumGameDev Sorry i described the situation wrong. I have 3 health and as soon as the trap activates i lose all 3 health. I have the damage set to 1 so i assume something is telling it to do that damage over and over in quick succession. I have my s set to 1 and changing them has no effect. also the firetrap active time has no effect as i die instantly after touching the trap while it's active. It feels like as soon as i collide with the box collider it continuously calls for damage. Sorry if I'm not making sense or asking stupid questions, I'm learning as I go.

[@PandemoniumGameDev]

@@syris78 Sounds like the IFrames are not working properly. Can you take damage from other traps like the spikes while you're in invulnerable?

[@gurt6265]

These are the absolute best tutorials I've come across! Thank you so much for taking the time to make these! Can't wait for more! 🍻

[@pianoatthirty]

Another quick tip for beginners - instead of duplicating the spikes, just change the Draw Mode on the sprite renderer from "simple" to "tiled" - then just drag out the image to the left or right for the amount of spikes you'd like to see!

[@andrewvan-heerden359]

[@peterwojtek8468]

I'll join the crowd in saying your tutorials are spot on ! I'm learning Game Development mainly for sound design purposes -as I have currently no clients as a sound designer, I'm planning on making my own game and your lessons provide an excellent template for making a more in-depth platforming game.

[@gamingforthefun3744]

Great Tutorial. One quick thing. I advise everyone to create two colliders for the firetrap. One is the box collider, for the trap itself, and the other is a capsule collider, for the fire. That way, you can activate and deactivate the capsule collider as the trap activates and deactivates, which allows you to recalculate if there's a trigger when the trap is triggered, and at the same time makes it so only the fire deals dmg, and not the trap itself. I made it like that and it works wonders. I have nothing else to add. Your tutorials have been helping me out tons

[@pianoatthirty]

another beginner quick tip - when you have to rename things (from fireballs to arrows for example), highlight the word, right click and select "Rename" and all your references in the script will also get renamed.

Quick performance tip. When checking if a collision hit the player using `if (collision.tag == "Player")`, Do: `if (collision.CompareTag("Player"))` instead.

[@unloadedmaster1176]

Why does this help with performance?

[@_57u]

@@unloadedmaster1176 if you only compare strings then unity/C# will create a duplicate of the string using the 'getter' of the object in question (will be allocated to the heap and need to be garbage collected), taking up space and time. Also, using compareTag will not create the need for extra memory allocation and will simply throw an error if the tag doesn't exist - where a string comparison wouldn't (resulting in a bug you'd have to find).

26:22 'if you would turn the trap around it would still work correctly' - If anyone couldn't get this to work, you have to make the rotation of the arrow trap -180, while the sprite remains at -90. Then it will work. You can also make it -90 and pop it in the ceiling too

[@calvinbirch7547]

These vids r so awsome keep it up! Would love to see you implement a double jump mechanic and possibly sliding down walls, like in many other 2D platformers, so you have to keep moving or else you will slide all the way down.

[@PandemoniumGameDev]

Double jump, coyote time and adjustable jump height is planned for episode 11. Sliding down walls it also a good idea, will experiment with it

[@garrettbates9124]

I experimented a bit and found that wall sliding can be easily implemented by changing the body.gravityScale from Zero to any positive number.

[@andrewvan-heerden359]

If you wanted the spike head to go only vertically up and down like i did: 1) comment out all directions in the directions array apart from -transform.up (now spike head can only travel up or down, so it's now an array with only one value) private void CalculateDirection() { // directions[0] = transform.right * range; // right direction // directions[1] = -transform.right * range; // left direction // directions[2] = transform.up * range; // up direction directions[0] = -transform.up * range; // down direction } 2) create a new variable: Vector3 originalPos; (to send spikehead back to start) 3) create a start method, and add: originalPos = new Vector3(gameObject.transform.position.x, gameObject.transform.position.y, gameObject.transform.position.z); private void Start() { originalPos = new Vector3(gameObject.transform.position.x, gameObject.transform.position.y, gameObject.transform.position.z); } 4) create a new method (mine is named restart) and add: gameObject.transform.position = originalPos; private void restart() { gameObject.transform.position = originalPos; } 5) in the Stop() method, add: Invoke("restart", 2); // the restart method will happen after 2 seconds private void Stop() { // stop the spike head, so it doesn't travel forever destination = transform.position; // stop moving attacking = false; // no longer attacking Invoke("restart", 2);//this will happen after 2 seconds } kinda teleports back, but it works

Hello @Pandemonium. I have a problem with the ArrowTrap. My ArrowTrap starts shooting Arrows before I enter the room where the ArrowTrap is.

Trying to turn a singleplayer game into a multiplayer is usually a bad idea. If you're going for a multiplayer you should start planning for it right away because the differences in the code are very big, so I don't see this tutorial turning into a multiplayer one. Maybe another one in the future.

Could anyone tell me why you can't stand on top of the spikes? They have a box collider so surely the player would be able to stand on top off them, but they just pass straight through them.
