I wonder if somebody could explain to me how Skidracer's excellent 'Pixies' code works. After much puzzling I still can't understand what is going on with it, especially this bit:magic=CreatePivot(camera) NameEntity(magic,"pixiespace") aspect#=Float(viewheight)/viewwidth PositionEntity magic,-1,aspect,1 scale#=2.0/viewwidth ScaleEntity magic,scale,-scale,-scale magic=CreatePivot(magic) PositionEntity magic,-.5,-.5,0 and especially especially the line: magic=CreatePivot(magic) Any help would be much appreciated. Full code here: http://www.blitzbasic.com/codearcs/codearcs.php?code=773 |

| as magic was previously used for: magic=CreatePivot(camera) which creates a pivot parented to the camera entity... when he then uses magic=CreatePivot(magic) it creates a second pivot with the first pivot as its parent... notice that he uses NameEntity(magic,"pixiespace") so that he can find the first pivot again not a great fan of this method of coding myself. |

| Ah. Thanks. So he's just reusing the handle instead of creating a new one for the second pivot? I thought there might be something clever going on there which I didn't understand. You're right, that does seem like a slightly odd way to code. Still, it works. What about the rest? How does all the positioning and scaling stuff work? |
