Unfortunately this mod doesn't work now and I can't try it.

Can you make it so fire can spread but it's very unlikely or possibly based on temperature?

The new update has fixed the issue. Thanks.

Displacedyooper and Juicy America, it was likely that you were loading in machines with Build Surfaces, which as Besiege warns is an experimental feature. Possibly as a result of their being experimental, Build Surfaces happened to have some inconsistencies under-the-hood as compared to the other blocks, which caused some adverse reactions with Thermal Fire. I have just pushed a patch that should resolve your issues, but if they are still present please provide more detail in your error reports. "This breaks my game when I spawn in machines" is not very helpful, at the very least please provide the output of the debug console.

This also broke my game. It only spawns in half of machines followed by freezing completely.

This completely broke my game. it didnt allow things to be spawned, deleted blocks and breaks surface blocks.

Big Mathis, I do not have the time to create a mod only one person will enjoy. I suggest you learn modding and create such a mod yourself. If you contact me on the Besiege Discord then I wouldn't mind providing you the source files of Block Health Removal Tool to help you, though.

Thanks but do you think you could make a mod that only does that as a default? Just for me. I really need a mod like that.

Wow, this really nerfed my long-range microwave radar (flame thrower radar that detects planes and burns it). I agree with you, that flame throwers are one of the cheapest and most savage way of destroying vehicles far away, its extremely OP. I remember annoying players with this method. Great job at making it realistic!

Big Mathis, I already have. It's called Block Health Removal Tool.

Do you think you can make a mod that will prevent grenades/explosive cannonballs from breaking cannon connections?

Awesome!
