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