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

[goh]

Then, you'd have to make the flight ability, which is the most complicated part. The easier way is to make an object, call it "obj_mario_capefly", and have Mario turn into this object if he jumps when his P-Meter is full. You should open an emulator and load a SMW Rom and play with the cape feather to see exactly how it works. As far as I remember, when Mario is flying, if you press the arrow button opposite to Mario's direction, he flies higher, if you press in the direction he is going at, he falls faster and causes an earthquake when he hits the floor.

I can't give you a script for this now since I don't remember the variables Hello Engine has and I still use an old version of Game Maker. But, there is a modified engine called "Hello Engine 6 Fan-Made" which has the cape power-up, if you can find it you can copy and paste it into your game!

I tried creating the obj_cape animation. But suddenly happens to become this:

Code:
