Game Maker Studio 2: Tower Defense Game 3/3

[@Cablesfish]

The code in the function scropt now has to look like this in the latest GM (2.3) function mouseOver(xx,yy,width,height){ if(mouse_x > xx && mouse_x < xx + width){ if(mouse_y > yy && mouse_y < yy + height){ return true; }else return false; }else return false; }

[@novato5106]

Actually just use point_in_rectangle

[@Cablesfish]

@@novato5106 Oh yeah. That'd be even better :)

[@nickdaiz1111]

I love you

[@danech7445]

@@novato5106where would you add that

[@apelike]

if (point_in_rectangle(mouse_x,mouse_y,x - sprite_width/2,y - sprite_height/2,x + sprite_width,y + sprite_height)) { return true; } else { return false; }

[@MinecraftEnthusiast]

Can you please extend this please? this is by far the best tower defence series out there! show us how to add different enemies after certain levels

[@CoreyHardt]

In your o_spawn object, the alarm[0] is where the enemies are created for each wave. So inside of your alarm[0], before creating the enemy instances, you'd want to have a check to see what level it was, and then decide which enemies to make. So for example: if global.level > 2 { instance_create_depth(x,y,-1,o_enemy2); } else { instance_create_depth(x,y,-1,o_enemy); } This code would check to see if the player is past the 2nd level or not. If they are past the 2nd level, it's going to spawn a new enemy type that you would make an object for and call it "o_enemy2". And inside of that object you can make their speed faster or give them more health.

@@CoreyHardt Yes, very nice

[@Mando37408]

This is amazing I would enjoy a extra episodes for extra enemies tower different tracks etc.

[@patch298]

I've discovered some neat things (with my version of the code at least) of bugs and kind of just interesting artifacts. 1.) If you click a tower to place and click another tower to place, (if you have enough money) they will stack and it makes 2 towers in the same place. 2.) If you have enemies coming into the range, the tower instantly shoots if it is the only enemy in range. Therefore, the tower can attack faster with a "worse spot" on the map barely having any range than just having batter range for right as the enemy spawns. 3.) Your towers can attack when the enemy is off screen, like if you extend the end path for longer than the map, and if the tower can reach that section, then the tower continuously attacks there until it is dead, so you can go onto the next wave. Which is why it is important to have a game over screen if the enemies reach the end of the track.

[@lidedn7555]

Dude, the first problem is easy to solve. Just check the box "solid" on all towers and in "step" write this: if(place_meeting(x,y,oCaminho) or not place_free(x,y)) //place_free(x,y) checks if there is any solid object in the specified coordinate, in this case touching our object { color = c_red; } else { color = c_white; }

[@larryteslaspacexboringlawr739]

thank you for gamemaker video

[@froggothecommentator8036]

Can you please make a part 4 about tower upgrade

[@CornerBlimkie]

Can you make an episode on making different types of enemies for the towers to shoot at? That would help me out so much!! Love your content btw, keep up the good work🙂

[@epiczeven6378]

wow! a fully working td in 1 day. I´m very impressed, Thank you so much for this :)

[@PhoenixLondon]

my enemies keep coming in before the previous wave is killed, what did I forget to do???

[@AndrewLeksche]

Alarm 1 for Obj_Enemy "if (instance_number(obj_enemy)

[@ItsNat21_]

I know this tutorial is old, but you should've made the towers snap to a grid or something like that, to make it semi-neat

[@sunstreak_games]

This set of tutorials was really helpful! Someone made a FOURTY PART tutorial for tower defense and I think that this is way better. With this, you're just setting up the basics of gameplay and you're free to do whatever you like with the rest of it. With the other one there is a lot less you can do because pretty much everything is already done for you. I have been adding a bunch of stuff to the project I'm working on while waiting for this part. Also I'm really happy that you put my idea into the video! Thanks for the tutorials!

[@minegamerzado2115]

can you send the part 4 video?

[@Nurk0m0rath]

I'm surprised you used object parenting but didn't even mention the benefits of doing your code in the parent object. You could have done all your game logic coding *once*, in the parent, and had the different towers simply inherit that functionality. Literally the only things you'd have had to change from the parents would be the objects created by the click and drag and the range and attack speed of the placed towers, along with the sprites of everything. You could have even used the tower 1 set as the parent, rather than creating an extra object. I mean, for this project I get that parent coding wasn't necessary, but this is a tutorial and the more complex the logic and the more variants that exist, the more valuable parent coding becomes.

[@jonathanmaynard2551]

RealTutsGML can you please do another Java game development series and have it be a survival game? If so can you also have it contain a procedural 2D terrain generation plz? Thanks

[@williamsfamily3947]

I really appreciate your tutorials and your commitment to this channel. I know you have been under criticism but don’t give up! So much blood is SUPER fun! People who don’t understand it are just that, people who don’t understand it. Thank you so much. See you in the next tutorial.

[@TylerH69]

Please can I put in a request... Please could you make a tutorial where you can have a start menu and a closing menu?

[@psirenvct]

thank you for this tuto mate, that's the perfect way to dive in the game's coding world!

[@andreasnara]

after my tower wiped all of my enemy, the second wave started but it only spawn one enemy, not six. Can someone help? I did everything the same way as the video says

[@JonathasCosta]

Awesome tutorial. Congrats!

[@owenhobbs1758]

first

[@scratchnmix9511]

Very nice and concise series. I wish you went more in depth on polishing aspects of it like animation/sprites as well as different enemies and more weapons.

[@0kr4m]

is it just for me but the parent object isn't working :/

[@hotgates9324]

Thanks for this great tutorial. Question. Is there a way to create a script that checks where the path is to see if we can place a tower or not, instead of using objects?

[@MyGameplay]

how to add background sound,how to ad a new map if i killed 20levels or so,so many things to do xD u ever end this project?

[@TylerH69]

Hi just to recommend Shaun Spading for sound. Have a look at the Platformer Tutorial that he created and there's a whole tutorial on adding sounds :-)

[@diegohorseman152]

Hello! Great Video! How can i create an .apk??

[@destroyergaming5205]

how would you add 2 different enemy types

[@zitnya3348]

it works but for some reason enemies will stop to spawn after round 24. Anyone knows why?

[@SirFeeshy]

I think it just crashes the game, so you can try and code it so that once you get to that wave they win the game or something.

[@samuellimin161]

in the last part when I run tower 1 2 and 3 it doesn't shoot and kill the enemy all the scripts are correct, where is the mistake sir? Please help

[@TylerH69]

I've literally just looked at that tutorial Samuel and my games perfect. If you look carefully, you will see that you have an error - probably either spelling or grammar area :-)

[@nutboybootiecoot7464]

I have a question, if I have two different enemy's at once(oEnemy1 and oEnemy2) in the range of a tower the tower will continue to shoot the first target(oEnemy1) then when the target is killed it will never lock on or shoot oEnemy1 instances, and will lock on the oEnemy2 and shot. But the problem to that is it will disregard Alarm0 and rapid fire oEnemy2. Could you help me with this?
