How about some thing like this

//Check if enemies are in range and activate firing if needed

{
if firing > 0 firing += 1;
if firing >= 30/rate firing = 0;
if not instance_exists(target) target = noone;
if instance_exists(ob_enemy)
{
if target = noone target = instance_nearest(x,y,ob_enemy);
if point_distance(x,y,target.x,target.y) > range
target = noone;
else if firing = 0
firing = 1;
}


if instance_exists(ob_enemy2)
{
if target = noone target = instance_nearest(x,y,ob_enemy2);
if point_distance(x,y,target.x,target.y) > range
target = noone;
else if firing = 0
firing = 1;
}

if instance_exists(ob_enemy3)
{
if target = noone target = instance_nearest(x,y,ob_enemy3);
if point_distance(x,y,target.x,target.y) > range
target = noone;
else if firing = 0
firing = 1;
}

if instance_exists(ob_enemy4)
{
if target = noone target = instance_nearest(x,y,ob_enemy4);
if point_distance(x,y,target.x,target.y) > range
target = noone;
else if firing = 0
firing = 1;
}

if instance_exists(ob_enemy5)
{
if target = noone target = instance_nearest(x,y,ob_enemy5);
if point_distance(x,y,target.x,target.y) > range
target = noone;
else if firing = 0
firing = 1;
}


if firing = 1 depth = -3;
else depth = -2;
}

i figured it out.

I just needed to make the other enemies the child of the original enemy

[flamses1000]

i need help so the tower will point at the enemy and shoot when an enemy comes by i looked back,but it didnt work for me

[TDsDomain]

how do you make it so the wave ends when all the enemies are dead instead of a time limit?

[guowei]

Awesome tower defend tutorial just some of the code bug me to no end, but that is just me:P

Thanks to your tutorial I'm able to complete my tower defense much faster then if i'm doing it alone Thanks alot!

[the_recruiting]

Sorry to bring this topic back up but does anyone have a working link to the file? Really important as this was a great tut!

Thanks

[flamses1000]

Please someone help me with my with rotating the towers

[OrangeDragonOrigami]

This is the best td tutorial i have found so far.
But i seem to be having problems with understanding how to add more towers.
I'm not that familiar with GM code.
This tutorial helped me understand more about GM code.
But can someone help me with adding more types of towers?
Also does anybody now how to make a bomb weapon that has a target in the middle and can blow up an enemy like in 'interceptor' "the swc" but this is followed by the mouse and after used once is not used again until ypu buy another one.
Like the bomb used in 'warzone tower defence' (for a better explanation).
By the way im using Game Maker 8pro.

[flamses1000]

how do you make it so the wave ends when all the enemies are dead instead of a time limit?

you would have to change the wave system to do this:
{
globalvar ee;
if wave_time = 600
{
wave += 1;
wave_time = 0;
wave_enemies = min(5+floor(wave*0.4),25);
ee = wave_enemies;
}
//Creates enemies
if wave_time < 600 wave_time += 1;
if wave_enemies > 0
{
if(wave_time = (ee-wave_enemies)*30+30)
{
switch(floor(wave/1))
{
case 1:instance_create(-32,0,ob_alien); break;--change ob_alien and other stuff to what ur enemies are if u want only one change all to same
case 2:instance_create(-32,0,ob_alien); break;
case 3:instance_create(-32,0,ob_alien); break;
case 4:instance_create(-32,0,ob_huge_spaceship); break;
case 5:instance_create(-32,0,ob_enemy); break;
case 6:instance_create(-32,0,ob_enemy); break;
case 7:instance_create(-32,0,ob_alien); break;
case 8:instance_create(-32,0,ob_enemy); break;
case 9:instance_create(-32,0,ob_huge_spaceship); break;
case 10:instance_create(-32,0,ob_alien); break;
case 11:instance_create(-32,0,ob_alien); break;
case 12:instance_create(-32,0,ob_tank); break;
case 13:instance_create(-32,0,ob_alien); break;
case 14:instance_create(-32,0,ob_huge_spaceship); break;
case 15:instance_create(-32,0,ob_enemy); break;
case 16:instance_create(-32,0,ob_tank); break;
case 17:instance_create(-32,0,ob_alien); break;
case 18:instance_create(-32,0,ob_enemy); break;
case 19:instance_create(-32,0,ob_huge_spaceship); break;
case 20:instance_create(-32,0,ob_alien); break;
case 21:instance_create(-32,0,ob_alien); break;
case 22:instance_create(-32,0,ob_tank); break;
case 23:instance_create(-32,0,ob_alien); break;
case 24:instance_create(-32,0,ob_huge_spaceship); break;
case 25:instance_create(-32,0,ob_enemy); break;
case 26:instance_create(-32,0,ob_tank); break;
case 27:instance_create(-32,0,ob_alien); break;
case 28:instance_create(-32,0,ob_enemy); break;
case 29:instance_create(-32,0,ob_huge_spaceship); break;
case 30:instance_create(-32,0,ob_alien); break;
case 31:instance_create(-32,0,ob_tank); break;
case 32:instance_create(-32,0,ob_alien); break;
case 33:instance_create(-32,0,ob_alien); break;
case 34:instance_create(-32,0,ob_huge_spaceship); break;
case 35:instance_create(-32,0,ob_boss); break;
if wave>= 35
room_goto(rm_menu)--change this to what u want like game_end()

}
wave_enemies -= 1;
}
}
}

[jak2027]

Quick question, how would one going about to change the Wave system so it spawns a number of enemies you choose instead of using the equation in the curent wave system?

[The Rock Abdo]

Great Tutorial Thanks VERY MUCH

[DioFlare]

Thanks! Nice tutorial!

Moved to Staff Choice for all the effort in the .doc and incremental gmks

[Terrified Virus]

Wow, this is awesome, I might just use some codes in my game! This definitely deserves to be in the staff choice section.

[_223916]

How do you add different levels (maps/rooms)?

[skibbi]

I'm a noob and I haven't a clue how to make this!
Please give permission to mod it if we give you lots of credit and don't enter it in anything!

[Nocturne]

I'm a noob :laugh: and I haven't a clue how to make this!
Please give permission to mod it if we give you lots of credit and don't enter it in anything!

Everything submitted to the turorials forums is for using! The idea is that you take it apart, learn from it then put it back together again in your own games, or create your own version based on this... so go ahead, but remember that CREDIT is an important part of the tutorials forum and so thank the member in your game for their help/engine/whatever...

[NestoFlo]

Great job! My father wants me to learn GML and coding, so this will definitely help out!
Its way better then hitting the apple haha.

[LVSF3]

I don't know why I'm getting this error:

dist = point_distance(x,y,target.x,target.y)/24;

at position 47: Unknown variable x

(second x variable)
(in step event of bullet tower)

Please help!
