banana engine is a 2d graphics engine.

currently supported

- basic shape rendering

- texture rendering

- rendering to a framebuffer

- input detection (keyboard and mouse)

- bitmap font

I'm currently researching strategies to implement a gui system.

Check out the `examples` dir...

### drawing a triangle

`go run ./examples/triangle`

```golang

import (

	"github.com/dfirebaugh/banana"

	"golang.org/x/image/colornames"

)

const (

	screenWidth  = 240

	screenHeight = 160

)

func main() {

	banana.SetWindowSize(screenWidth, screenHeight)

	banana.Run(nil, func() {

		banana.Clear(colornames.Skyblue)

		banana.RenderShape(&banana.Polygon{

			Vertices: []banana.Vertex{

				{

					X:     0,

					Y:     float32(screenHeight),

					Color: colornames.Red,

				},

				{

					X:     float32(screenWidth / 2),

					Y:     0,

					Color: colornames.Green,

				},

				{

					X:     float32(screenWidth),

					Y:     float32(screenHeight),

					Color: colornames.Blue,

				},

			},

		})

	})

}
