Castle Game Engine

Strategy Game Demo using CGE and Tiled

I’m happy to present a new large Castle Game Engine demo: “Aliens vs Humans”. It is a simple strategy game with maps designed using Tiled.

The demo is in the examples/tiled/strategy_game_demo/ directory of our source code. You can also download precompiled versions for Windows or Linux.

Our Tiled maps API was enhanced with various methods to make writing games easy:

These methods work for all map orientation types (hexagonal, orthogonal, isometric, isometric staggered). This way you can handle e.g. hexagonal and orthogonal maps the same way, with the same code, without worrying about the differences how “neighborhood” is defined differently for hexagons (6 neighbors) and orthogonal maps (4 or 8 neighbors, depending on CornersAreNeighbors).

The user interface is designed using Castle Game Engine Editor. The game code uses TUIState to split the game into states. Each state UI is loaded from a separate .castle-user-interface file. Thus, this is also a demo of how to use TUIState with CGE editor, to organize a larger game into states.

This demo was requested by Castle Game Engine supporters on Patreon. I took some time to make it, as I wanted to make it perfect 🙂 If you’d like to see more crazy CGE demos, join us on Patreon!

Castle Game Engine

SpriteSheet GUI utility

A new application to manipulate sprite sheets: https://github.com/valterb/spritesheet-utility , thanks to Valter Buccina!

It is a GUI application for Windows.

You can:

  • Load the necessary images and create the spritesheet.
  • Flip and resize individual images (with or without constraints of proportions). It might be useful for creating spritesheets in the opposite directions.

  • For resizing it is possible to set the interpolation mode in those proposed in TResizeInterpolation.

  • Finally you can load a spritesheet and see the animation. Frame sizes are automatically calculated based on the number of frames and columns. It is possible to change frames per second during the animation.

The application is made using Castle Game Engine, with TCastleImage, TGLImage, TCastleControl and TSprite.

See the related forum thread.

With big thanks to Eugene Loza, we can celebrate new year with a new game using Castle Game Engine!
