changing collision masks

hi folks

im stumped on the best way to accomplish this....I have an object in many layouts....but for one of the layouts I want to replace this object with a different image....and a different collision mask. it seems the only way to do this is to create a different object as you cant change collision masks during game....

so how should I do this? ive got a "main" event sheet that controls the behaviours of the object in all the layouts....so I cant just replace the object in the main event sheet or it wouldn't work in other layouts....

I want only one of the several layouts to use the different image and collision mask....

any ideas?

thanks!!

Add a new animation to your object add the new image to the new animation and change the collision mask for that animation.
