what best way draw grid this using spritekit 2d game engine? requirements: input programatically number of columns , rows (5x5, 10x3, 3x4 etc.). draw programmatically using skspritenode or skshapenode , since using images of square this doesn't seem efficient me. the squares should have fixed size (let's each 40x40). the grid should vertically , horizontally centred in view. i'm planning use skspritenode (from image) player moving in different squares in grid. so, i'll save in 2 dimensional array central point (x,y) of each square , move player's current position position. if have better suggestion too, i'd hear it. i appreciate solution in swift (preferably 2.1), objective-c too. planning on using on iphone devices. question close to one . appreciated. i suggest implement grid texture of skspritenode because sprite kit renders grid in single draw call. here's example of how that: class grid:skspritenode { var rows:int!
