Having a problem with instance_destroy()... please help [SOLVED]

[Ned Madigan]

So heres the deal, I am very new to gml, like very new. I am trying to make a the object destroy when its health is too low. But, when there are multiple of the same object in the room, they will all act as the same thing... they will all be destroyed. Is there a way to make it so only the object affected will be destroyed:
This is in the step event of, obj_enemy.
if healt<0
{
instance_destroy();
}

your code should only destroy the instance calling it. Can you show the code where you deal damage to this object?

I assume you are using the 'health' variable.
Unfortunately, the health variable is a global variable shared by all instances.

So rather than 'health', try using 'hp' or 'my_health' or whatever.
It doesn't really matter, as long as it's not a built in variable.

players code:
if place_meeting(x+2,y, obj_enemy) && sprite_index= spr_hit
{
obj_enemy.sprite_index= spr_enemyhit
}

enemys code:

if sprite_index= spr_enemyhit
{
healt-=1
}

....
- sprite_index=spr_enemyhit is the animation played when you hit the enemy

did you actually use "healt" or did you mean "health"?
if you are using "health" (with an h) then that's a global variable and is always the same no matter what object calls it.

edit. didn't see your last post.
you say obj_enemy.sprite_index and if I'm not mistaken that will change it for EVERY enemy.
this means every enemy has it's image set to hit and all enemies lose their hp.

I purposely made it "healt" so it wouldnt be the health global variable

I made it healt so it woudlnt be global

obj_enemy.sprite_index= spr_enemyhit

The is is your problem here.
NEVER use object.variable.
Remember, objects don't store variables, instances do!

Instead, use the collision functions to get the id of the instance you collided with, and use that to get the variable.

Or easier; use the collision events and use 'other' to refer to the instances you collided with.

yeah i just noticed your second post. I edited my post. It's because of how you're changing the sprite_index

Ok thanks will try

 

[Soso]

yeah when you say obj_enemy.(variable) your accessing that var for every instance of obj_enemy

if you put your code in the collision event you can use other.(var) since other is specific to that collision

example

///Collision event

other.healt -= 1;

also this code here your using will minus 1 from healt every step of the game that sprite index == spr_enemy_hit

if sprite_index= spr_enemyhit
{
healt-=1
}

Ok i will see if it works thanks

Yes thank you so much it worked, thanks everyone as well, as i said i am very new to gml.
