Is it possible to directly delete terrain with lua without having to create any kind of particles?

Not by any means I know of.

Alright, thanks.

Yeah, the best way (I've found) is to use MOSRs set to EraseFromTerrain and then immediately deleting themselves.

EraseFromTerrain? What is that?

A function.

It clears terrain that exists behind an object. Think of it as using an object as a cookie-cutter.

Never heard of that function. I'll test it.

It's called by the engine whenever a deepcheck returns true afaik fwiw.

My little tool just use that code. I'd thought of using invisible MO to delete the terrain(not to shoot it by invisible mopixels), but failed to find a feasible way .

I guess that it would be better to do that things the old way. I mean, ini diggers have always worked fine, so why bother in something more complex?

Unless I wanted to use that function for something else, of course, like some bunker buster bomb or something like it.

Because I want to find a solution of digging ultrahard terrain materials, such as "Laser Barriers" in MP3. You can set the sharpness of digger particle to over 99999999 or what , but it's not so effective, because the traditional way of digging usually leaves out some small terrain particles, which could totally block you in that StructuralIntegrity. Since the sharpness is such high, the digger will be way too overpowered in fightting and could easily lead to game's crashes/lags.

That last point, my tool isn't made for gold digging. Thus, the way it works is the best solution I can think of.
