Thanks 3RUN.
Specifically is 'effect_sprite available in *.wdl?
if so, where?
It's only available in lite-c, so I'll try to convert it, but only tomorrow (it's 01:39 am here).
If you want, you can give it a try yourself too, search for 'particles.c' in the root folder of game stutio.
Best regards
Edit: I took a look at the script, but I'm afraid my c-script knowledge isn't good enough to do this, cause I completely forgot everything since I switched to lite-c
My advice to you: switch to lite-c as soon as possible, it's very easy to migrate (you will spend few days max) and it's much better! You are missing a lot of functionality while using c-script.
