Sticks walls and corners
-
Hi,
I got a problem. I'm trying to create a "saw" which is sticks the walls, but i don't know how to make this :
I'm using an FlxTilemap for the level, and I want the saw to go all around the level. I do not know if it's understandable...
Maybe the better is to use FlxPath with raycasts ?Thanks for your help !

Solution 1.
FlxG.collide(saw, level)and then checkisTouching(FlxObject.LEFT),isTouching(FlxObject.UP)and so on. Based on them set current velocity.
Solution 2 (better). At level launch: get yourself a starting tile and go tile-by-tile checking neighbour tiles for being the wall, like the saw, but ignoring positions between tiles. When you know your tile-by-tile path, you'll easily get point-by-point one to follow.If you need some details on how to analyze the tilemap tile-by-tile you can check here: http://www.imageprocessingplace.com/downloads_V3/root_downloads/tutorials/contour_tracing_Abeer_George_Ghuneim/alg.html
BTW, by "not OK" you mean this is incorrect saw behaviour, or it's correct too, but you're not sure how to achieve?

I mean "I don't know how to make it" ^^
I'll see your link, thank you :)

PS : Your 1st solution, that what I made. But, it doesn't works well in the 2nd case
