Ok I feel REALLY stupid asking this but I can't find out how anywhere!!
I want to be able to make my character disappear. Isn't there something like cEgo.visable = false or player.visable = false some where?
If I don't misremember, there's an undocumented Character.on parameter, which can be set to true or false. For the player, this is the same as changing the ShowPlayerCharacter property in the room editor. You can also use Character.Transparency = 100 to make a character invisible.
Another option would be to set the character to some co-ordinates like (-1000,-1000).
Make a big walk-behinde area.
All of the above will work, as will changing the character's view or loop to something containing blank sprites.
Using transparency means the character can still be clicked on; the other options won't. Well, unless you have pixel-perfect turned off, but it's on by default.
Thank you all ;D I'll figure out which one will be the best way for me.
