when i create a terrain in MED and open it in GS Extra A6, compile and run, the terrain appears completely black, even after texturing and adding lights, wats wrong???

I have another question, how come sometimes u can add scripts and sometimes u cant, became everytime i go to map properties>add script, the button is grayed out and i cant click it, what do i have to do to allow it to add script??

You need to apply a texture to your terrain. By default, the texture will be all-black. The way you add a texture depends whether or not you have the public beta (caution: beta releases have bugs) as 6.31 uses a different method than 6.40.2 does.

In either version:
1. Create your texture. Textures must be a power of 2. That is, the width and height must be either 16, 32, 64, 128, 256, 512, 1024, 2048, or 4096 pixels. 256x256 is the fastest, but they don't have to be square as you can have 512x128, 2048x1024, or 32x64.

In 6.31 and earlier (your likely scenario as all-black was the default used in 6.31):
2. Access the skin edittor through the menus at the top (I don't recall which one, but I think it's the edit menu).
3. From in the skin edittor go file > import skin. If you used a TGA or PCX file instead of BMP, make sure you choose that file type from the drop down menu, find your file and double-click it to open it. Your terrain is now textured.

In 6.40.0 or later (unlikely your case as 6.4 has the option to go fully untextured, which is the default):
2. Go to edit > manage skins.
3. Click new skin, check texture, then click the texture file button, then the ... to browse for your file. Find it and double-click your file (make sure you have the correct file type from the drop down menu if you don't use the default chosen (normally BMP)). Your terrain should be textured. If it isn't, continue on.
4. Click the select all tool in face mode, return to the skin manager, choose the texture to use, then click the "set skin" button. At this point, it should definitely be textured.



As to your other question, save your file first and after saving the file, you can then add a script to your level.

thanks alot : )

another question, after adding A6 script to my level, and i tried to add a action to premade map entities AND some that i made by myself, but when i click on the folder button in properties>behavior, there were no actions to be chosen, it was completely blank, help!

also, i keep on getting error messages such as 'script error, engine shut down' even when trying to run techdemo.wmp i haven't done anything to it, it says lik
weapon.wdl 185:3 error(218): Sound/Music disruptor_zap zap.WAV not found
<camera_solidpass=1>
TECHDEMO.WDL 105:0 error(63) Parameter unknown camera_solidpass
.....

Techdemo is an older file using the a5 templates. you may need to update these templates to work with an the A6 update. The other problem is probably that you have not added the player templates to your A6 project. The A6 templates have fewer actions defined than the a5.

sry, im sort of new at this, can u tell me how to add player template or w/e template to my project?

ok, so this is the thing, all the original scripts such as A6 contain no action or behavior when i try to assign them to a model, but A5 has all the actions, BUT everytime to try to compile and run on A5 script, it says lik weapon.wdl error, zap_zap not found thing, engine shutdown, so i want to get my models actions and behavior but i cant because there are no actions in A6, when i click properies behavior, its completely empty, while A5 always has error whenever i try to run,why is that???? someone plz help!

You should take a look at the "Project Manager" in the file menu.
(If you don't find it, update to latest version of Game Studio.)

You also find A6 template scripts in "GStudio6\template_6\code" folder.
Adding "plBiped01.wdl" should already help a lot. By adding this script GStudio automatically includes other scripts required for player actions.
