The Block is hurting the player If he got an Item for example a Mushroom
Block made by SquidMan Tool used - Blockreator
Give Credits please ^^
Rejected for three reasons:
It's a powerup filter but has got a major flaw in which you can bypass the filter if you have a star, fly through it with the cape or flashing because the hurt routine won't run under these conditions. It'll also kill you when you ride Yoshi which... isn't a good design unless you're designing a kill on Yoshi block (which doesn't seem like it here).
The powerup filter is almost identical to lose_powerup.asm except it properly filters out Mario's powerups and Destory Yoshi is a better example of a Yoshi filter.
It's created with Blockreator which outputs unoptimised codes. Please code the blocks on your own instead of using Blockreator. Even then, you still check how every possible powerup state in SMW which not only is highly unoptimised (remember that each conditional branch has got an inverse) but also makes it incompatible with custom powerups.
