I guess this thread is still active as it is 'sticky'
I started with AGS some weeks ago, so here's things I would have loved to stumble upon earlier than I did (some AGS specific, others general scripting).
… oh, and I leave the wording to one of you guys
- you don't need {} brackets if there's only one action after a condition
- want your character.say() not to time out? Change the behaviour in 'General Settings'
- lots of rooms looking the same/similar? create a basic room, right click and make a template out of it (god I wish I'd known that one earlier!)
- walkspeed 10 means a character moves 10px on each game cycle (at least that's what I heard)
- a quick&short note that about 1 second having 40 game cycles on default settings
- interested in a specific feature? take the time to read into it (manual!) or search the forum. most things are wasy enough to understand even for new scripters if they're willing to concentrate.
