Terraria base: GameMaker Studio

Get started making a terraria-style game!

This project includes:

•  basic terrain generation with perlin noise. (Noise script included)
• Simplified terraria-style lighting using surfaces, a radial gradient sprite for the light source, and a blur shader for additional smoothing.
• And basic 16 frame bitmasked autotiling.

Everything is commented with the exception of the player code as I do not expect you to keep it in there, and the blur shader as it's more on the complicated side. All you really need to know is how to apply it, which is included in the code comments.

I have always searched for something like this to lead myself in the right direction, however all options out there are extremely complicated for max performance or simply not compatible with how I generally make my games. This is a great base for intermediate programmers looking to try to develop something like this.

Additional suggestions:

• You should definitely add chunking for creating large terrains, it is not covered here but it's essentially creating small versions of the worldgen code and storing them in a grid/array, then rendering and updating them only if that chunk is within the view.

• I did not supply background tiles, but it can be included in the current list by changing the terrain grid from only indexing the single block value, to an array or struct.
  • Array: grid[X][Y] = [0, 0] // Index 0 is the foreground, index 1 is the background.
  • Struct: grid[X][Y] = { fg: 0, bg: 0 };
  • Then updating all other areas where the grid is accessed to be compatible with the new form
  • Alternatively you can just create another array for the background grid
