How would I go by creating a realistic driving experience?
I'm using iOS Swift 3 with SpriteKit using the functions applyForce to accelerate when I click the gas button and when braking I add friction to the physicsBody, also I can't seem to turn right, no idea on how to do it.
Right now for turning I'm splitting the screen using the left and right to turn but I'm using applyForce but its very bad because it turns when the car is stopped and in a very unrealistic way.
When I apply force its only to go up so if I do create a turning mechanism and I do a uturn the car will still go up.
Also side note: Multitouch doesn't work?
Any help? Thanks
override func didMove(to view: SKView) {
// Multi Touch
self.view?.isMultipleTouchEnabled = true
car.carNode.position = CGPoint(x: 0, y: 0)
car.carNode.physicsBody = SKPhysicsBody(rectangleOf: car.carNode.size)
car.carNode.physicsBody?.affectedByGravity = false
car.carNode.physicsBody?.angularDamping = 0.1
car.carNode.physicsBody?.linearDamping = 0.1
car.carNode.physicsBody?.friction = 0.1
car.carNode.physicsBody?.mass = 1
self.addChild(car.carNode)
// HUD Display
gas.gasButton.position = CGPoint(x: 300, y: -500)
self.addChild(gas.gasButton)
brake.brakeButton.position = CGPoint(x: 150, y: -500)
self.addChild(brake.brakeButton)
}
override func update(_ currentTime: TimeInterval) {
if touching {
car.carNode.physicsBody?.applyForce(CGVector(dx: 0, dy: 180))
}
}
override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
for touch in touches {
let location = touch.location(in: self)
if location.x < self.frame.size.width / 2 {
// Left side of the screen
car.carNode.physicsBody?.applyForce(CGVector(dx: -100, dy: 0))
} else {
// Right side of the screen
car.carNode.physicsBody?.applyForce(CGVector(dx: 100, dy: 0))
}
// Gas Button
if (gas.gasButton.contains(location)) {
touching = true
}
// Brake Button
else if (brake.brakeButton.contains(location)) {
car.carNode.physicsBody?.friction = 1
}
}
}
