This is what i do:
map properties-> new script -> gs6 -> template -> war

then

add model->properties -> behavior -> action ->player_walk_fight
-> build -> run -> can't run WAR.WDL -> why?

also are there any tutorials for 3dgs a7?

For example, where are Lite-C tutorials:
When you are on the Gamestudio Community Forum pages, you can see at the top of the left side one word: Links.
Just move your eyes little bit downward, and you can see a text Online Tutorial. You dont have to do more just click on the text, and suddenly you will be teleported to the tutorial site.

you `d better used lite-C to dev Game.

1.file/Map Properties
2.set script for .wdl or .c file

Download the lite-c workshop from the 'Downloads' page, that will give you a good understanding into lite-c scripting.

is there any step by step turotial developing games using 3DGS7?
