GateEngine Demos

Example projects for GateEngine, a cross platform game engine for Swift developers.

Navigating this Package

Projects are organized as their own executable. Each project is a single swift source file.
There are no "helper" functions or dependences.

Available Examples

General

1. User Input: Show text when using certain user inputs.
2. Multiple Windows: Open multiple windows on compatible platforms.
3. Save State: Save and restore game state.

2D

1. Animated Sprite: An animated sprite loaded from assets.

• Pong: A virtual table tenis clone.
• JRPG: Uses Sprite, TileMap, Scripting, and StateMachine.

3D

1. Rotating Cube: A textured cube loaded from assets.
2. Skinned Character: An animated character loaded from assets.
3. Mouse Picking: Changes the color of an object under the mouse cursor.

• First Person: Move around a level with mouse and keyboard controls.

gateenginedemos's Issues

Github.io Demo Site

Create a repository for a github.io page and auto build the demos.

The README has a bunch of broken links (to demos).

When you click on three of the hyperlinks in the README that link to the individual demos, you get a GitHub 404 page instead. The first three demos (User Input, Multiple Windows and Save State) have broken links. The links for the 2D and 3D demos are fine.

Error in `IOKitGamePadInterpreter.swift` causes build failure

I'm seeing the following error:

Access level on imports require '-enable-experimental-feature AccessLevelOnImport'

I first saw it in my own project after updating to 0.2.0, but it also happens when I try and build this demo repo. I can build again by reverting my project to GateEngine 0.1.2.

Assertion Failure Upon Launch for one 2D and All 3D Demos

Project cloned from this repository. Running 2D_01_AnimatedSprite executable runs into assertion failure upon launch:
GateEngine/Entity.swift:50: Assertion failed: Component "SpriteComponent" is not a member of this entity.

Stack trace:

Similar crashes for all 3D demos, but rather with component Transform3Component:
GateEngine/Entity.swift:50: Assertion failed: Component "Transform3Component" is not a member of this entity.

Crashes occurred on simulator as well, so I'm hoping it's just an issue with the logic. Nonetheless here is machine details:
2021 MacBook Pro (M1 Pro chip)
macOS Ventura 13.5.1
Swift version 5.7.2
Xcode 14.2
