haloob is an Out Of Box (oob) implementation of the hal interface for Bellina.

HAL stands for the Hardware Abstraction Layer

It uses the g5 package for its graphics implementation.

Through an object that implements the hal interface, Bellina can interact with the OS window and be aware of window resize, mouse, and keyboard events.

hal is how Bellina creates an initial window with a given dimension and title.

go get -u github.com/amortaza/go-hal-oob

In your application, call bl.Start(...) to start Bellina. bl.Start(...) requires a hal interface implementation.

haloob.NewHal() provides an object that implements the hal interface.

See example/haloob-example.go for a complete application

NOTE: haloob's implementation uses GLFW, which requires runtime.LockOSThread() in init()

import "github.com/amortaza/go-bellina"
import "github.com/amortaza/go-hal-oob"

func init() {
	runtime.LockOSThread()
}

func main() {
    hal := hal_g5.NewHal()()
    bl.Start(hal, 800, 600, "Title", onInit, onTick, onUninit))
}

func onInit() {
    // Initialize my app
}

func onTick() {
    // Update app state
}

func onUninit() {
    // Free memory in my app
}
