|
|
GESTE is a sprite and tile 2D render engine designed to run on
|
|
micro-controllers low performance systems. GESTE also provides a basic math and
|
|
physic engine using fixed point arithmetic.
|
|
|
|
## Creating maps
|
|
|
|
GESTE is developed in parallel with
|
|
[tiled-code-gen](https://github.com/Fabien-Chouteau/tiled-code-gen), a tool
|
|
that generates code from the [Tiled Map Editor](https://www.mapeditor.org/).
|
|
|
|
## Examples
|
|
|
|
The crate `geste_examples` contains 3 examples of different game genre:
|
|
- platformer
|
|
- RPG
|
|
- racing
|
|
|
|
## Design
|
|
|
|
### Layers
|
|
|
|
In GESTE, a scene is made of layers. Native layers can be `Sprite`, `Grid` or
|
|
`Text`. You can implement you own type of layers if you want to.
|
|
|
|
- `Sprite` layers display a single tile at a given position
|
|
- `Grid` layers display a grid of tiles at a given position
|
|
- `Text` layers display a text at a given position
|
|
|
|
Layers have a priority which tells in which order they will be drawn on the
|
|
screen.
|
|
|
|
### Rendering
|
|
|
|
The rendering algorithm is somewhat similar to ray casting. Instead of taking
|
|
each objects of the scene and drawing it on the screen, the engine takes each
|
|
pixel and tries to find its color from the different objects of the scene.
|
|
|
|
For each pixel of the area that is being drawn, GESTE will go through the list
|
|
of layers and see if the corresponding pixel inside the layer is transparent or
|
|
not. When a non transparent pixel is found, the pixel is pushed to the screen
|
|
and the procedure starts again for the next pixel. If all the layers have a
|
|
transparent pixel, the background color is used.
|
|
|
|
The more layers to go through, the more time time it will take to render a
|
|
pixel.
