Enhance rotate and zoom UI #112

CrafterSvK · 2023-08-06T15:47:31Z

Hello, I've been trying to get a hold of the codebase, so I've chosen the simplest thing I could think of.

Zooming in and out using buttons and mouse
Rotation
Zoom buttons should be disabled on min/max zoom

Rotation is currently handled by multiple keyboard input handlers which do separately things (rotate camera, rotate isometric objects). Need to merge to one keyboard handler which sends signals to other handlers.
In my opinion it would be lazy to solve this by making a global emitter, for these kinds of things, maybe that's right, I do not know. Or just make button to click rotate_left, rotate_right key :)

CrafterSvK · 2023-08-07T00:24:49Z

Every WorldThing can now react to rotation of camera. Maybe the emit to Global camera rotation from buttons can be directly made in TabWidget so there will be no need to signal it through PlayerHUD to CameraControls.

CrafterSvK · 2023-08-13T18:33:10Z

Buttons are now disabled on max/min zoom. It's handled using Global singleton, maybe refactoring to different Singleton would be better. Or if you find another way to do this, I would be glad.

There are a few issues remaining, otherwise it looks fine.

I addressed the issues, thanks

The signal connection syntax was simplified in the previous PR, so it should be here too. Please also rebase to the master branch, and when everything done, squash all commits into one containing the PR message only.

Hello :) !

Please read this doc first https://docs.godotengine.org/en/stable/tutorials/inputs/inputevent.html

A thing that need to be said is checking inputs with _input, in _process or in _physics_process is really different.

You can test the code bellow by example

extends Node var i = 0 var j = 0 func _input(_event): i += 1 func _process(_delta): j += 1 func _notification(what): if what == NOTIFICATION_WM_CLOSE_REQUEST: prints(i, j)

_input is only called when an event occur. That mean it also not respect frame rate.

_process try to respect frame rate.

_process_physic follow frame rate.

So, we need to be pretty meticulous when we change the behavior of something in _input

 	elif event.is_action_pressed("zoom_out"):
-		if _camera.size < ZOOM_OUT_LIMIT:
-			_zoom(ZOOM_VALUE)
+		_zoom_mouse(ZOOM_VALUE)


It is preferable to do that in _process func.

It is not recommanded to call the func rotate. Chance is a "Node" type, but "Node2D" have a rotate func.

Please read https://docs.godotengine.org/en/stable/tutorials/physics/ray-casting.html#d-ray-casting-from-screen

Also you can use math(Pythagore) instead physics engine. You know your plane is always on Y = 0.
Not same, but can help you https://github.com/theludovyc/Godot_DestropolisLike/blob/1081bde949fd27e9d43eb0d3e4cfa5e36faa1b8a/Script/Camera3D.gd#L15

If _on_TabWidget_button_rotate_left_pressed() is already called by signal, is not great to re-send a signal from it.

Signals with Godot is great powers, so come great responsability.

Try to use less as possible, they have cost on performances.
