I know others have run into the same issue. But I was wondering if there was a way to resolve this so that I don't have to manually type/paste the name of the action? It kinda slows down the work progress when I have to dig out the script and find the action name for certain entities...

Even though they're not listed, it compiles and runs fine when I put the action on the entity manually.

Have you save the main .wdl or .c file?
Have you add your script to WED: File->Map Properties->Main->Script?
Have you add #include statement on top of your script?
Have you add PATH statement to locate your script files?

... yes...

I'm NOT a 3DGS noob. (signup date... ? Hint.)

I have this problem with one project too, cause i saved the script in a different folder (../scripts). I can still type in the actions but it won't listed. It's not that bad but i couldn't find any solution for this problem/bug yet.

Seriously irritating bug.. I've seen it with actions, but now I have it with materials sigh..

Somebody sent the problem my way. Suddenly today my actions are not showing up in WED.......aarggghh!
