GameSwiftEngine

Simple engine for 3d

Features: Collision, dynamic shadow map, bones animation.

Models format: OBJ, IQE

Demo

Unfortunately you will have to use your resources to run the demo

Editor

You can edit the scene in the editor. With ObjectEditor you can save and load the scene state and edit it (see EditorDemo). You can add to the editor your own objects inherited from Node with custom fields (see DoorNode).

Fast instruction

Added SMP

    .package(url: "https://github.com/shsanek/GameSwiftEngine.git", branch: "main")

Added import

import GameSwiftEngine

Create MetalView

let metalView = MetalView()

Added metal view in classic UIView

parentView.addSubview(metalView)

or you can use SwiftUIView

SwiftUIView {
    metalView
}

Сreate a SceneNode and attach it to the loop in you MetalView

let sceneNode = SceneNode()
metalView.controller.node = sceneNode

Use base node for to fill the stage scene

let texture = Texture.load(in: "Asset name")
let object = Sprite3DNode(texture: texture, size: .init(1, 1)) // generate plane
sceneNode.addSubnode(object)

BaseNode

• Node - base node
• SceneNode - root node for render, contains main camera
• Sprite3DNode - simple 3Dmodel node, supported texture and vertex geometry
• Object3DNode - 3Dmodel node for IQE (see InterQuakeImporter), supported texture and vertex geometry, and bones animation
• LightNode - node for light controll
• CameraNode - for render in texture or main camera

NodeAnimation

NodeAnimation - animation description, NodeAnimationController - for control animation

• NodeAnimation.empty
• NodeAnimation.move - for change position object
• NodeAnimation.updateFrame - for control transition frame in Object3DNode
• NodeAnimation.sequence - combines multiple animations

var animation = NodeAnimation.move(to: .init(x, y, 0))
animation.duration = 1
controller = container.addAnimation(animation)

Matrix

For simplicity, there are several functions

• perspectiveMatrix
• translationMatrix4x4
• rotationMatrix4x4
