Since im new at this I figure I will make a list of things I want to know how to do:
1. How do you place multiple textures? Because when I select the texture in the texture menu, the whole map gets covered in that texture. I want it only to cover parts I select.
2.How do you add working water? When I do it crashes the game when the map loads.
3.could someone explain a little bit more about the walker vehicle scripts? Like what do each of these numbers mean here? AddWalkerType(1, 0) -- 1x2 (1 pair of legs)
Sorry, yes i'm really new to this but im getting it all down.

Steps 1 and 2 are covered in the FAQ thread at the top of this forum. Look for 'How to make your first map ' in the second post.

The third question is answered in the documentation. Look in the Mission Lua Guide.

Ok, i've get the other stuff down and now I need someone to tell me why there is a huge bright white light appearing around the player when the map loads? There is no models currently in the map, the map is 2 flag ctf. Basically the map is a big arena with a yavin temple texture.
