1)How to make dialogs like in King Quest or Neverquest? I know you can choose it, but which option is it? and where to put "talking faces"?
2)How to make random people walking(Like in Pleurghburg on streets)
3)How to make invisible GUI background? When I choose background image, it's still on GUI's Background?
1) you put the talking face sprites in a different View, and select that as 'talking view' for the appropriate character. Then use DisplaySpeech ().
3) you can make them transparent when importing the relevant sprites.
2) You can use the "MoveCharacterPath" command for this (see manuals for details). If they should walk "really" randomly, use the Random(x) function as a parameter. One short example:
MoveCharacterPath(1,random(400),random(300))
will move character 1 to a random x,y position
