Scirra Construct is a 2D game development engine with a focus on building games visually. No programming is required though the software uses a visual method for event handling that relies on programming concepts like variables, loops and conditions. It provides a powerful form of scripting that's as easy as clicking, dragging and dropping.
The software is available in two version:
Construct 2 - a Windows-only software with a one-time purchase.
Construct 3 - a web app using a subscription for access.
The opensource Construct Classic is also available, but it is retired and no longer developed.
GDevelop is an open source game creation software, allowing to make games for the web (HTML5) or for Windows and Linux. No programming or coding skill is required! It is easy to use and powerful enough for advanced users.
Game logic is created thanks to an event based system, using conditions which have to been filled so as to execute actions. These events are compiled by GDevelop to machine code, as ordinary programming languages, making them simple but powerful.
Sprites, particles engine, physics engine, path-finding, joystick support, dynamic lights and many others features are available and are provided thanks to a built-in extension system allowing external developers to enhance GDevelop capabilities.
