When the brush is set to 1 px, it will not write. That other thing you said is not a bug, it's to show the wifi channel connections.

wikku is a noob... he checks out mods that have problems from the official version then blames us for those bugs when its in official too.

Does wikku even know how to code, or has he even tried?

He made VENT I believe. But, it's a basic element.

if(t==PT_VENT && pv[y/CELL][x/CELL]>0.0f)
pv[y/CELL][x/CELL] -= 1.0f;

if(t==PT_VENT && pv[y/CELL][x/CELL]<0.0f)
pv[y/CELL][x/CELL] += 1.0f;

That's all the powder.c needed. A freaking monkey could do powder.h.

Catelite already made the sim at the top

I made an issue on github, has the exact code that is having problem, right where it crashes.
