What it does

GDevelop is an open-source game engine that allows founders and developers to create 2D and 3D games without extensive coding knowledge.

When to use it
  • •When you want to create a 2D or 3D game without learning a new programming language
  • •When you need a cross-platform game engine that can deploy to multiple platforms
  • •When you want to create a multiplayer game with ease
Ready-to-paste prompt
Create a new scene with a player object that moves left and right using the arrow keys, and add a collision event to detect when the player hits an obstacle: `Create event > Add condition > Keyboard > Key pressed > Left/Right`
Heads up: GDevelop uses a custom JavaScript-like language for scripting, so if you need to create complex game logic or use external libraries, you'll need to use the 'JavaScript' event type and write custom code
