How to create custom SKActions?

Question

Hi everyone, what I want to do is create an SKAction that does something similar to a wheelRight.physicsBody.velocity = CGVectorMake(0, 1000);physical object.

Answer 1

Use the SKAction runBlock:method:

SKAction *changeVelocity = [SKAction runBlock:^{
        wheelRight.physicsBody.velocity = CGVectorMake(0, 1000);
    }];
SKAction sequence = [SKAction sequence:@[..., changeVelocity, ..., ...]];
[wheelRight runAction:sequence];
