zgui

zgui is a GUI system based on Constraints, which uses raylib.

Example

In zgui, a component definition is always preceded by a constraints definition (constraints) and the struct with the options of the component (BoxOptions).

display := zgui.GetDisplay()

constraints := zgui.DefaultConstraints()
constraints.SetY(zgui.NewCenterConstraint())
constraints.SetWidth(zgui.NewRelativeConstraint(func(x float32) float32 {
    return x * 0.3
}))

greenBox := zgui.NewBoxComponent(&zgui.BoxOptions{
    Color:     rl.Green,
    Roundness: 0.1,
    Segments:  20,
})

After describing the component, you can add it to a parent element. The root component is display.

display.Add(greenBox, constraints)

Finally, the raylib main loop should look like this:

for !rl.WindowShouldClose() {
    rl.BeginDrawing()
    rl.ClearBackground(rl.Black)

    display.Update(rl.GetFrameTime())
    display.Draw()

    rl.EndDrawing()
}
