Tip: Layer 3 backgrounds and tides disappear when you hit a message box, so plan your level around that. For example, you can add a sublevel without layer 3 at the start/midpoint, and include your message there.
A carryable POW switch similar to the one from SMB2. When triggered, and depending on a certain define in the ASM, it will either stun/kill sprites on ground like when you do a cape smash, or turn sprites on screen into coins, just like when you hit the goal tape in the end of a level.
The switch is carryable, too, and depending on the extra bit, you should either press it to trigger it or
throw it against something with a certain speed.
An optional ExAnimation file is also included, as well as a JSON file for PIXI 1.2 users.
Note that if carried through a pipe, it'll turn into a regular SMW blue POW, so you may want to avoid that.
Works pretty much as presented. The only problem is the P-switch reuse bug which works on it too (and additionally also becomes a non-functional p-switch if Yoshi eats the smoke) so I would suggest you to update the sprite and make it inedible once pressed.
This sprite is already made in Davrosís SMW Items 1.1. Can you please remove it and make it act like Sonís Mario Bros. Arcade POW block when you throw the sprite on the ground? And donít turn all sprite into coins.
