I’m using Xcode 8.3 and I’ve been having a few problems with getting the touchesBegan function to run.
I made a new game with SpriteKit. I then added a SpriteKit Scene called GameStart.sks. I created a corresponding Cocoa Touch Class.
From GameViewController.m I changed the line that starts GameScene to
GameStart *scene = (GameStart *)[SKScene nodeWithFileNamed:@"GameStart"];
When I ran in the simulator, it went to the GameStart scene (which I added a Color Sprite so I know it works).
From there, I edited the GameStart.m file and populated it with the following code:
- (void)didMoveToView:(SKView *)view {
}
- (void)touchDownAtPoint:(CGPoint)pos {}
- (void)touchMovedToPoint:(CGPoint)pos {}
- (void)touchUpAtPoint:(CGPoint)pos {}
- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
for (UITouch *t in touches) {[self touchDownAtPoint:[t locationInNode:self]];}
NSLog(@"touch works!");
}
- (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event{
for (UITouch *t in touches) {[self touchMovedToPoint:[t locationInNode:self]];}
}
- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event {
for (UITouch *t in touches) {[self touchUpAtPoint:[t locationInNode:self]];}
}
- (void)touchesCancelled:(NSSet *)touches withEvent:(UIEvent *)event {
for (UITouch *t in touches) {[self touchUpAtPoint:[t locationInNode:self]];}
}
Notice the touchesBegan I added an NSLog() line which should output “touch works!” to the console.
I run it in the simulator and when I click, nothing happens! When I do the sample one the touch works fine (from GameScene the “Hello World!”).
This lead me to believe I have setup GameStart incorrectly. Have I missed a crucial step?
