I'm a new Android developer that's developing a simple twist on the Tron game with GPS movement, but I'm having trouble implementing player's intersecting.
Right now, my player's trails are Paths that I move to co-ordinates and draw the co-ordinate difference as a line on the canvas. The path class offers no such intersection method that I can find, so I resorted to using Regions which I've tested an intersection to work with 2 regular Rectangles, but I can't make a Region using Region.setPath for some reason. From my understanding, the path needs to be closed to form an area for it to create a Region, which isn't exactly what I need. Is there a way to create a region off a path, and not the area the path creates? ie: If the path were a straight line of 10px thick, how do I make a region that is a line of 10px thick? Or alternatively, are there other ways to check for 2 paths intersecting? A short code sample: Path p1path = new Path(); p1path.moveTo(startPos,startPos); p1path.lineTo(newPos,newPos); p1path.moveTo(newPos, newPos); Region p1region = new Region(); p1region.setPath(p1path, new Region(0,0,480,800); // this is where the region isn't setting as I thought it would... // do same for p2 if(p1.quickReject(p2)) // checks for intersection Thanks :) -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
