1) how do I paint walls and floors in a different texture (im using the premade rooms)
2) can you easily import your own textures for walls and floors etc?
3) why do the floor textures appear on the ceiling and the ceiling textures on the floor?"
1) Use segment editor, load up the segment and retexture using a .tga file. .tga's can be created using Adobe's Photoshop or Jasc's Paint Shop Pro. There is a far more indepth guide to it in the forum's just browse/search for the post.
2) See above. It's sort of easy... with practice.
3) This is covered in the manual but not very clearly so Ill redo it in my own word's for you.
To paint floor segments press 'f' and this put's you into 'Floor Paint' mode. Now you can right cick to remove a current floor piece by piece or left click (with your choose floor tile) to place it piece by piece.
For ceilings you press '+' to go the floor ABOVE where your ceiling is and using Floor Paint mode you pain the ceiling tile's.
For example, Paint 4 floor tile's in floor paint more, press '+' and paint another 4. Test build and you should the floor and ceiling. To change the texture's from the prebuilt one's use the Segment Editior and look at the early text in this post.
Good luck with your game!
