PHP Code:

SPRITE    0          era_waterballoon1.png    0    0   32   32 shadow
SPRITE  200          era_waterballoon1.png    0    0   32   32 arrow up
SPRITE  201          era_waterballoon1.png    0    0   32   32 arrow right
SPRITE  202          era_waterballoon1.png    0    0   32   32 arrow down
SPRITE  203          era_waterballoon1.png    0    0   32   32 arrow left 


If I wanted to change the sprite index 200 to another image in say 3 seconds, how would I do that?

I've tried this: (doesn't work)

PHP Code:

SCRIPT
function onPlayerEnters() {
  findimg(200).image = "block.png";
}
SCRIPTEND 


Thanks
