how do you draw a health bar on top of an enemy and moving with the enemy and also make it separate. example: there is enemy 1 and enemy 2. enemy1 is the same object as enemy 2. but if i shoot enemy1 the health will decrease but enemy 2 will not decrease it would stay the same ok comprende he he he......

Righty ho.

To seperate their health (let's call it "hp") variables, just never change the value of "obj_enemy.hp" This applies to all obj_enemy's.

Instead, reference "hp" from the instance (e.g. on collision with bullet) or "other.hp" from another instance that has collided with it (e.g. on bullet collision with obj_enemy)

Now, to draw the healthbar:

2 options:

1) From the obj_enemy's draw event:

draw_healthbar(x-20,y-30,x+20,y-25,hp,c_black,c_red,c_green,1,0,0)

2) From a controller's draw event:

with obj_enemy
{
draw_healthbar(x-20,y-30,x+20,y-25,hp,c_black,c_red,c_green,1,0,0)
}

That do it for you?

[purple_pixie]

Or the hp to selfhealth - doesn't matter

i used this code draw_healthbar(x-20,y-30,x+20,y-25,HP,c_black,
c_red,c_green,1,0,0) that you gave him but my enemy seems to disapeer what could i possible have done wrong

using the draw event cancels the built-in draw event.
You have to tell the game to draw the sprite, using draw_sprite.

Remember, you could also make a seperate draw event, call it object draw. Then set on the player a global.life, then go to the draw step event
x = obj_player.x
y = obj_player.y

And put the code for the drawings in the draw event.

Good luck =)
