Hello, do you have any ideas for doing player sprite collision with sand simulation?? for example:

1. when character jump into sand, sand will fly to the sky
2. when character trap in sand, it will move slowly
3. hwen character move in sand, sand will change

The way I can think is read character pixel from viewport, and when the pixel is character, do collision logic. But I can not think clearly the logic

Hello， I think you should know noita. I see the videos about noita, and that is amazing! you can see some magic effects fly around the screen. I think they have similar logic with the sand simulation, but have no clear ideas. Do you have any idea to simulate such magic logic with sand simulation? such as :

1. spawn fire magic to hit wood and explode the wood
2. spawn laser to stone and later logic

thanks for sahring this good project.
but when i run enough time, i find some logic error. such as for water, when water falls down to ground, it should form horizontal plane quickly, but your water speed is too slow, so it is not like water, but like...ugh, maybe sand?

I think the problem is your speed. in your shader, you only move 1 pixel each time, this may limit something
