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

[SuperSledgeBro]

This is going to be very, very complicated. You should know exactly how the cape powerup works in SMW. I think you should get the cape animation working first. Then, the "slow fall" ability, which is similar to the raccoon leaf's. Put this code in the end of Mario's main actions script: (which is Event User 2 in Hello Engine if I'm not mistaken)

if keyboard_check( [jump button here] )
and vspeed >= 0.5
{
vspeed = 0.5
}
