I would like to use invisible trains in a "fun" mod I'm making. I would like to know if I can use some of the code in your mod for mine. I can also just create a fork with just the train functionality if you would rather have that. (I can't get the biters to work - I think they must have changed sprite size since this was made and I don't know how to find the new sizes since Macs are dumb and won't give me the image size when inspecting a file).

Yes, you can use my code with credit but I'm not sure how much use it will be to you; the reason I haven't updated the mod is all the sizes changed when HD graphics came out.

Trains still work invisible, and that's enough for me! Just a touch of things here and there make me happy. Thank you so much!
