How can I make a Cape power-up from SMW?

[goh]

Try changing:

"and (obj_flyingmario.sprite_index != spr_mario_cape_fly or not instance_exists(obj_flyingmario))"

into:

"and ((obj_flyingmario.sprite_index != spr_mario_cape_fly and instance_exists(obj_flyingmario)) or not instance_exists(obj_flyingmario))"

Nope, didn't work!

Code:
