Hi

I'm trying to draw a horizontal healthbar/meter with a sprite and the draw_sprite_part function. The sprite is 35x8, with its origin at 0,0, drawn at 181,12. The variable used (global.charge) has a max of 350. This code has had no success, nothing gets drawn.

draw_sprite_part(interface_meter,0,0,0,global.charge/10,sprite_height,181,12);
 

Does anybody know how to fix this?

Thanks in advance!

Hi

The title says it all! I have:

if instance_exists(enem_parent){...}
 

But how do i check at the same time if this instance is inside the room boundaries? Can't get my head around this...

Thanks in advance!

Hi

In my game, a sideweapon has to shoot the nearest enemy. All enemies have the same parent (enem_parent). This is in the step event:

var enem_nearest;
enem_nearest = instance_nearest(x,y,enem_parent);
 

And this is the code for the shooting itself, on an alarm event:

      if shots_left > 0{
         if enem_nearest != -1{
            with instance_create(x+1,y,obj_plship_bullet){move_towards_point(enem_nearest.x,enem_nearest.y,16);}
            instance_create(x+1,y-10,obj_plship_fire);
            shots_left -= 1;
            alarm[0] = 5;
            alarm[1] = 30
         }
      }
 

Why do I get the "variable unknown" error, while the var is clearly stated in the step event? Any ideas on how to correct this code?

Thanks in advance!

Hi

For my shmup i'm creating...

I have two sprites, one for the player's ship (not animated) and one for the player's ship when invulnerable after losing a life (animated; flashing white). When I want to change from the first to the second, nothing changes... How do I change to a sprite that animates?

This is my code, in an alarm event:

global.hp = 100;
global.exploding = 0;

vspeed = 0;
gravity = 0;

sprite_index = plship_go;
image_speed = 0.2;

x = 120;
y = 260;  

Also, my object stays on the given x and y; the player is unable to move while I don't see why...

Any suggestions?

Thanks in advance

Hi

I was wondering how to in/decrease any variable (score, health,...) not all at once, but in a small amount of time, so it's possible to see it changing one by one.

Figured this would be possible with some kind of for/while loop, but I don't exactly know how...

Any suggestions?

Thanks in advance
