9/18/2023 0 Comments Pin stack 3ds max![]() You will use the offset, absoluteOffset, and newSize variables to calculate the size of the new layer.The currentSize and currentPosition variables contain the size and position of the current layer. The previousSize and previousPosition variables contain the size and position of the previous layer.The direction will track whether the block’s position is increasing or decreasing, and the height variable will contain how high the tower is.Var previousPosition = SCNVector3(0, 0.1, 0) To do this, open ViewController.swift() and add the following variables right above viewDidLoad(): You’re going to add some properties to help you keep track of the blocks in play. Then use the assistant editor (hint: it’s the one with the two overlapping circles located at the top right of Xcode’s window) to add an outlet from the label to the view controller and name it scoreLabel:īuild and run to see what you have so far.ĭo you know what makes a tower taller and taller? Yep! Building blocks. Now switch to the Attributes Inspector and change the font to Custom, Thonburi, Regular, 50. Then add a constraint that aligns the label to the center, like so:Īdd another constraint that pins the top of the label to the top of the screen. Add a label on top of the SCNView and set its text to 0. Open Main.storyboard you’ll notice it already has a SCNView. You need a way to show the player how high they’ve stacked their tower. Now let’s spice it up with a cool background! With the base block still selected, switch to the Scene Inspector and drag the file Gradient.png to the background slot like this: You need to add a physics body to the base block, so switch to the Physics Inspector and change the physics body type to Static. In the Material Inspector, change the diffuse hex color to #434343.In the Attributes Inspector, change the size to Width: 1, Height: 8, Length: 1.In the Node Inspector, change the name to Base Block and set the position to X:0, Y:-4, Z:0.Drag a new box into the scene and apply the following properties to it: You’ll need a base block to support the tower as the player builds it up. Back in the Attributes Inspector, set the Position to X: 0, Y: 0, Z: 0 and the Rotation to X: -65, Y: 20, Z:-30: Since the camera is viewing the scene from one side, you don’t have to light the side you don’t see. Next, you’ll add some light to the scene.ĭrag a new directional light from the object library into the scene and rename it to Directional Light. Now switch to the Attributes Inspector and change the camera’s Projection type to Orthographic. Set the Position to X: 3, Y: 4.5, Z: 3 and the Rotation to X: -40, Y: 45, Z:0: Open GameScene.scn.ĭrag a new camera into your scene, then select the Node Inspector and rename the node to Main Camera. You’ll begin by setting up your game scene. Miss entirely, and it’s game over! Setting up the Scene Be careful though: Placing a block even slightly off will cause it to become sliced. The goal of stack is to place blocks one on top of the other. ![]() ![]() ![]() You’ll be creating a game similar to Stack. You’ll also notice the App Icon has already been added for you! :] Take some time to look around and get familiar with the project. In addition, there are some SCNVector3 extensions to perform simple arithmetic operations on vectors and a gradient image. Inside, you’ll find a SceneKit catalog filled with some audio and a scene file. Start by downloading the starter project. If you are beginning your SceneKit journey, check out our SceneKit tutorials as well as our beginning Swift tutorials. This tutorial assumes you’re familiar with SceneKit and Swift. Programmatically adding nodes to a scene.Have you ever seen one of those amazing 3D games that uses slick simplistic graphics and requires a steady timed tapping finger to create a fun and immersive gaming experience? With the power of SceneKit, it’s amazingly easy to create those types of games yourself! ![]()
