A friend and I are working on a mod project, and we started using one weapon from the Gun Template. It was just a test to see what we could do with it, but he keeps on getting this error:

Abortion in file .\system\contentfile.cpp. line 549, because:
failed to load data file object with following path and name
Private.rte\devices\sprites\PTRS-sprite-gun000

Any suggestions?

You either have a wrong filepath or only one sprite for the gun. In the that case you either need to make a firing sprite or find FrameCount = 2 under the sprite path and change it to 1

And if you're only using one sprite for the gun, you don't use 000 at the end of the filename.
000 is for nonfiring.
001 is for firing.

Thanks, but for some reason, he and I corrected some stuff and it was fixed. Ill keep all that other stuff in mind when creating more weapons. Many thanks!
