I tried play with spritekit in isometric grid. But i can't understand how to fix level.
import SpriteKit
import XCPlayground
let view:SKView = SKView(frame: CGRectMake(0, 0, 1024, 768))
XCPlaygroundPage.currentPage.liveView = view
func + (left: CGPoint, right: CGPoint) -> CGPoint {
return CGPoint(x: left.x + right.x, y: left.y + right.y)
}
func - (left: CGPoint, right: CGPoint) -> CGPoint {
return CGPoint(x: left.x - right.x, y: left.y - right.y)
}
func * (point: CGPoint, scalar: CGPoint) -> CGPoint {
return CGPoint(x: point.x * scalar.x, y: point.y * scalar.y)
}
func / (point: CGPoint, scalar: CGPoint) -> CGPoint {
return CGPoint(x: point.x / scalar.x, y: point.y / scalar.y)
}
enum Tile: Int {
case Ground
case Wall
var description:String {
switch self {
case Ground:
return "Ground"
case Wall:
return "Wall"
}
}
var image:String {
switch self {
case Ground:
return "ground"
case Wall:
return "wall"
}
}
}

placeTile2D(tile.image, withPosition:point)

}
func point2DToIso(p:CGPoint) -> CGPoint {

let scene:SKScene = GameScene(size: CGSizeMake(2048, 1024))
scene.scaleMode = SKSceneScaleMode.AspectFit
view.presentScene(scene)
In result i have:
But need draw block as level in matrix
As matrix levels:
let tiles = [
[6, 1, 0, 0, 0],
[1, 1, 0, 0, 0],
[0, 0, 0, 0, 0],
[0, 0, 0, 0, 0],
[0, 0, 0, 0, 0]
]
