I have a sequence where I have a SCNScene with one ship already in frame. The goal is to move a new ship in, pause, then smoothly move the camera to a new angle "over the shoulder" of the new ship and do the next step in the code. I get the new ship moving in then no next steps. The code is:
func startAttack() {
let moveAnime = SCNAction.move(to: SCNVector3(-20, 75, 75), duration: 0.5)
attShip.runAction(SCNAction.sequence([moveAnime, SCNAction.wait(duration: 0.5)])) { self.positionCamera() }
}
func positionCamera() {
print("got to position camera")
if Thread.isMainThread {
print("already main thread")
self.overwatchCamera.runAction(SCNAction.customAction(duration: 1, action: { node, timing in
node.position = SCNVector3(-75, 300, 300)
node.look(at: SCNVector3(20, 75, -75), up: self.rootNode.worldUp, localFront: self.rootNode.worldFront)
})) {
self.doAttackRound()
}
} else {
DispatchQueue.main.async {
print("reset to main thread")
self.overwatchCamera.look(at: SCNVector3(20, 75, -75), up: self.rootNode.worldUp, localFront: self.rootNode.worldFront)
self.overwatchCamera.runAction(SCNAction.move(to: SCNVector3(-75, 300, 300), duration: 1)) {
self.doAttackRound()
}
}
}
}
I tried testing for whether it was on the main thread already, and in my testing it is showing that it gets to the position camera function but it is not on the main thread and tries the option with the DispatchQueue. I left in both of the ways I have tried to execute the camera movement animate, through a custom animation on both the position and look at for the camera, and through a static change to the look at and an animated move of the camera position. Neither one is triggering.
Any help would be greatly appreciated. Thanks!
