I'm trying to create an object with 1 of 2 sprites, a left or a right version, based off of an object that isn't moving.

I have a series of objects that represent 1 spear. The spear on the ground I pick up and hold, the spear that's thrown in the air, and the spear that sticks into the wall/objects.
I have it set up so that the spear turns with my character. If I face left the spear uses the left sprite, right gets the right sprite. The ground/held sprite and the in the air sprite all tell the next object what sprite to use.

Now my character can walk up to a spear in a wall and pull it out. The spear drops to the ground and then I can pick it up.
This is the code I use to pull the spear out.

if global.SpearInHand = 1 { exit; }   //checks to make sure you can only have 1 spear and not pull another spear out of the wall
if global.SpearInHand = 0						 
{
  if collision_rectangle(x-22,y-3,x+53,y+2,MyCharacter,1,1) >= 0   ///makes sure you're touching the spear
  { 
   instance_create(x,y,spear); instance_destroy(); exit; 
  }  
}

I know I can use i = instance_create(x,y,spear); with (i) { bla bla bla }
I'm not sure what variable I can check to see which sprite is used by the spear in the wall.

Any ideas?

Well asign a temporary variable to spear and then use that to change it´s sprite image depending on your character... eg

var nnn;
nnn=instance_create(x,y,spear);
if sprite_index=spr_left nnn.sprite_index=spr_spear_left;
if sprite_index=spr_right nnn.sprite_index=spr_spear_right;

Is that any help?

EDIT: If there are more than two directions you could do this with a switch statement which is more efficiently...eg

var nnn;
nnn=instance_create(x,y,spear);
switch (sprite_index)
{
case spr_left:
nnn.sprite_index=spr_spear_left; break;

case spr_right:
nnn.sprite_index=spr_spear_right; break;

etc...
}

Wow, not sure why I didn't check. I thought sprite_index was write only. Didn't even bother to see if I could "ask" what it was.
I got it working now, thanks.

No problem... Glad to help!
