How do I do a solid that kills you in platformer behavior?

Just something like Mega Man spikes that are solid and kill you if you touch them is something I need to do.

I don't need to know how to create a death sequence, I already did that. I just need to know how to trigger it if a platformer touches a specific solid object.

Most Mega Man games had solid spikes.

Seemingly from testing I just did related to what you said, we have to use overlapping at offset and the offsets something like Platformer.Platform.VectorX * Platformer.dt and I'm guessing the platformer's vector Y needs always set to 10 when standing so it detects when standing on death traps too.

These are the spikes I remember where he jumps in front of them because theyre on a layer behind, I don't see how that is a solid object? youtube.com/watch

So if you create spikes sprite, don't set it to solid you can use player on collision with spikes.

They were intangible in 1, but pretty sure nearly all the other games after had solid death tiles including Flame Man's burning oil tiles that act like spikes that I clearly remember were solid even though that's really weird. To be honest, in terms of NES, there was only one background layer and the spikes in 1 just had no collision detection.

It seems to work though if you use offsets like I mentioned. Just keep it in mind for future reference I guess? You might want to do it later as well.
