Sprite Overlays #608

Closed SpyrexDE closed 2 years ago

SpyrexDE commented 4 years ago

Describe the project you are working on:

I am working on a pixel-art top-down shooter with focus on animations.

Describe the problem or limitation you are having in your project:

I want to make sprite overlay animations. But Godot is only able to do that using shaders, what realy is a pity.

Describe the feature / enhancement and how it helps to overcome the problem or limitation:

There could be a feature for that like how it is in GameMaker: (https://www.youtube.com/watch?v=ZrvKmDpVP6I) or maybe a "Sprite Overlay"-Node. I would prefer the second option.

Describe how your proposal will work, with code, pseudocode, mockups, and/or diagrams:

The "Sprite Overlay"-node could be a node you can put as a child on a Sprite-Node. It inherits from the normal sprite node and there could be some extra options I don't know at the moment because I am extremely new to programming.

If this enhancement will not be used often, can it be worked around with a few lines of script?:

I saw a lot of Indiegames using sprite overlays. But depending on the engine they are used more often because there is a feature like this. It would help a lot of people to develop their games. I already asked for a sloution on reddit(https://www.reddit.com/r/godot/comments/flshso/is_there_a_way_to_create_sprite_overlays_in_godot/) but only received a way to do that with shaders. And when you do it in that way you are not able to animate the sprite overlay.

Is there a reason why this should be core and not an add-on in the asset library?:

Because it is an elemental feature you can use in nearly every game. In addition to that you can include it into the node/scene-system what effect, that you can put overlays on overlays, animate/tween them or get the input the overlays received.

I think this could be a blend mode of CanvasItemMaterial.

EDIT: Maybe not directly a blend mode, because those are specifically chosen because they are very fast. An option like "add onto parent" in CanvasItem would be better.

Related proposal: #470.

Also it seems like people are coming from GameMaker and Construct background.

Not exactly sure, but isn't this masking? Would be great to have built-in, I agree, would save a lot of time.

This now exists as the CanvasGroup node in the master branch. CanvasItem clipping can also be achieved using the relevant property in CanvasItem in master, closing.
