How to determine the type of an InputEvent?

[Ullanar]

Hi!

Here is simple code snippet from examples

func (p *Player) Process(delta gd.Float) {
	Input := gd.Input(p.Temporary)
	//...
}

gd.Input returns classdb.Input. I want to create function which handles all inputs and returns action name which should be processed into my state machine.

So i want to make function like

func (p *Player) HandleInput(event gd.InputEvent) {
       // trying to handle mouse modes
	if event.AsInputEvent().IsActionPressed(p.Temporary.StringName("ui_cancel"), true, true) {
		mouseMode := gd.Input(p.Temporary).GetMouseMode()
		if mouseMode == gd.InputMouseMode(0) {
			gd.Input(p.Temporary).SetMouseMode(gd.InputMouseMode(1))
		} else {
			gd.Input(p.Temporary).SetMouseMode(gd.InputMouseMode(0))
		}
	}

    // rest of strange code to collect movements
}

How can I get that gd.InputEvent type from classdb.Input? And also specific InputEventMouseMotion to handle rotation?

You can switch on the underlying event type and access the derived godot class like this:
(I also recommend capturing Input and tmp variables and using the named enum values to make the code more concise and readable)

func (p *Player) HandleInput(event gd.InputEvent) {
	var (
		tmp   = p.Temporary
		Input = gd.Input(tmp)
	)
	if event.IsActionPressed(tmp.StringName("ui_cancel"), true, true) {
		mouseMode := Input.GetMouseMode()
		if mouseMode == gd.InputMouseModeVisible {
			Input.SetMouseMode(gd.InputMouseModeHidden)
		} else {
			Input.SetMouseMode(gd.InputMouseModeVisible)
		}
	}
	// Switch on the underlying event type.
	switch event := tmp.Variant(event).Interface(tmp).(type) {
	case gd.InputEventMouseMotion:

	case gd.InputEventMouseButton:

	}
}

I understand it's not obvious how to do the type switch, so I appreciate you reporting your experience here and I will be considering ideas on how to make this more intuitive.

Thank you! Also in question I wanted to ask about gd.InputEvent type. In HandleInput in this case we need to accept event param. What is the way to get it?

Implement the UnhandledInput(gd.InputMethod) method on a Node.
