#PHYSICSEDITOR WILL GET A SPRITE KIT FOR ANDROID#
Swift support for Android is in development.
#PHYSICSEDITOR WILL GET A SPRITE KIT CODE#
It has support for iOS and OS X, and it also supports Android through the SpriteBuilder Android plugin provided your code is written in Objective-C. Cocos2DĬocos2d is a free, open-source framework, compatible with both Swift and Objective-C. Note that we only focus on the 2D aspects of these platforms. After reading this article, you will have several options to choose from to make the next big hit. For instance, the following code creates a radial gravity field: SKFieldNode fieldNode = SKFieldNode.CreateRadialGravityField () įieldNode.Position = new PointF (Size.Width / 2, Size.In this article, we explore several game engines and frameworks, highlighting some of the key advantages each of them offers. This causes the bananas to oscillate like a spring around the field node:Īdding a different field is similar. Node.PhysicsBody = SKPhysicsBody.Create (node.Texture, node.Size) Var node = SKSpriteNode.FromImageNamed ("TinyBanana")
Var touch = touches.AnyObject as UITouch
You can then add sprites and set their PhysicsBody properties so that the physics field will affect the sprites, as the following code does when the user touches the screen: public override void TouchesBegan (NSSet touches, UIEvent evt) Spring Fieldįor example, the following code creates a spring field and adds it to the scene: SKFieldNode fieldNode = SKFieldNode.CreateSpringField () įieldNode.Position = new PointF (Size.Width / 2, Size.Height / 2) įieldNode.Region = new SKRegion(Frame.Size)
SKFieldNode also has properties to control field attributes such as the field strength, the field region, and the attenuation of field forces. You can create a spring field by calling SKFieldNode.CreateSpringField(), a radial gravity field by calling SKFieldNode.CreateRadialGravityField(), and so on. There are a variety of factory methods on SKFieldNode to create different physics fields. Physics fields are created using the SKFieldNode class, which is added to a scene just like any other SKNode. These allow you to add things such as vortex fields, radial gravity fields and spring fields to name just a few. The effect of tweaking the alpha threshold like this fine-tunes the previous collision, such that the monkey falls over when colliding with the banana:Īnother great addition to SpriteKit is the new physics field support. For example, the following code results in a slightly different physics body: sprite.PhysicsBody = SKPhysicsBody.Create (sprite.Texture, 0.7f, sprite.Size) The alpha threshold defines the minimum alpha value a pixel must have to be included in the resulting physics body. In addition to simply setting the PhysicsBody property directly to the geometry derived from the texture, applications can set and alpha threshold to control how the geometry is derived. Sprite.PhysicsBody = SKPhysicsBody.Create (sprite.Texture, sprite.Size) Alpha Threshold Simply call SKPhysicsBody.Create with the texture and size: SpriteKit makes creating such a physics body possible with a single line of code. This makes it easy to implement collisions that look more natural.įor example, notice in the following collision how the banana and monkey collide nearly at the surface of each image: SpriteKit now supports deriving the physics body of a sprite from its texture. Every sprite has an associated physics body ( SKPhysicsBody) that defines the physics properties such as mass and friction, as well as the geometry of the body in the physics world. SpriteKit includes a 2D, rigid body physics API. In particular, the new physics features make it very easy to add realistic effects to a game. These include integration with SceneKit, shader support, lighting, shadows, constraints, normal map generation, and physics enhancements. SpriteKit, the 2D graphics framework from Apple, has some interesting new features in iOS 8 and OS X Yosemite.
