Applying Coefficient of Restitution in a collision resolution method

阅读更多关于 Applying Coefficient of Restitution in a collision resolution method

问题 I have a collision resolution method in my physics engine, that goes like this: Vector2 n1pos = n1.NonLinearSpace != null ? n1.NonLinearPosition : n1.Position; Vector2 n2pos = n2.NonLinearSpace != null ? n2.NonLinearPosition : n2.Position; Vector2 posDiff = n2pos - n1pos; Vector2 posDiffNormal = posDiff; posDiffNormal.Normalize(); float totalRadius = n1.Radius + n2.Radius; float posDiffLength = posDiff.Length(); float interPenetration = totalRadius - posDiffLength; float averageRestitution =

问题 I'm am trying to drop the SKSpriteNode with constant speed and without bouncing. Here is the code I'm using: SKSpriteNode *floor = [SKSpriteNode spriteNodeWithColor:[UIColor clearColor] size:CGSizeMake(self.size.width, 1)]; floor.physicsBody = [SKPhysicsBody bodyWithRectangleOfSize:floor.size]; floor.physicsBody.restitution = 0.0f; floor.physicsBody.dynamic = NO; floor.physicsBody.allowsRotation = NO; SKSpriteNode* block = [SKSpriteNode spriteNodeWithTexture:[SKTexture textureWithImageNamed
