Title: Loader.loadOBJ Problem
Post by: AGP on October 31, 2017, 08:33:08 pm
Code: [Select]
System.out.println("\n\n\nWarcraft.loadObject: "+fileName +" Is the mtl null? "+(mtlFile==null));
System.out.println("Is loadOBJ(fileName, mtlFile) null? "+(Loader.loadOBJ(fileName, mtlFile, .5f)==null));

Produces:
Quote
Warcraft.loadObject: buildings\castle_construction0.obj Is the mtl null? false
Exception in thread "main" java.lang.NullPointerException

I've opened the file in Blender and it loads just fine.

mtlFile might be not null, but does the actual file exist? For desktop jPCT, it's best to set the Logger to ON_ERROR_THROW_EXCEPTION, so that it exists early. jPCT-AE already does this, the desktop version just doesn't for compatibility reasons. Maybe that reveals the actual problem.
