[Rseding] [0.17.75] Crash with RollingStock wheels direction_count of 0

[Muppet9010]

If you set RollingStock's wheel's direction_count to 0 the game crashes when you hover the RollingStock over a railway track and the game tries to draw the wheels.

data.lua code used to reproduce the issue:

Code: Select all

data.raw["cargo-wagon"]["cargo-wagon"].wheels = {
	direction_count = 0,
	filename = "__core__/graphics/empty.png",
	width = 1,
	height = 1
}

The example code sets that value to 1. Does a value of 1 or a value of 0 reproduce the crash?

thanks, corrected. value of 0 is what causes the crash.

Thanks for the report. It's now fixed for the next version of 0.17. I also made it so wheels are optional and you can just not define them to not have them draw.
