feature request: ability to set slot alpha and other slot methods

[blurymind]

It would be very useful if we can affect various slots in a dragonbones asset via gdscript.
Ability to set slot opacity, set blend mode, even replace slot image.

These features seem to be missing in the runtime at the moment, as the methods are not exposed to gdscript

DB provide lots of API to support Avatars System for different requirements.

1. change slot display index
   slot.displayIndex = xxx
2. change slot display directly
   slot.display = xxx
3. change slot display from db factory (to ensure pivot is set by designer in DBPro)
   armatrue.replaceSlotDisplay(xxx,xxx,xxx, slot)
4. change mesh texture
   armatrue.replaySlotDisplay(xxx,xxx,xxx, slot)
5. change textureatlas
   armature.replaceTexture()

here are some examples

possibly this could set opacity and color modulate?

gddragonbones/gddragonbones/src/dragonBones/armature/Slot.h

Line 334 in 5e12611

bool _setColor(const ColorTransform& value);

Was having some fun digging around and looking at your commits to see how you expose the methods

My C++ experience is not yet up to the level though

Here are some examples from dragonbones forum,on swapping sprites on slots

@blurymind I thinks it's right, but I need some time to return for updating module with new functionality. It's better to test now current version for get stable version, than we can go further.
We need TODO list for brilliant ideas.

[blurymind]

@sanja-sa thank you. I will test the module more extensively and see if I can catch any more crashes or bugs. It seems to be quite stable at the moment btw

Hello @sanja-sa!

I was just checking out your addon's issues (no offence), and for the easiest means of using DB anims in Godot, this feature is quite important. Hence, I also request that this gets implemented, as some of my anims require this.

That's all! Have a nice day!

[blurymind]

@sanja-sa Is this something you have time to work on?
As I see it we can probably do that with godot's native polygon2d node.
What would be great is to get and importer for dragonbones files that converts the data to godot nodes

Hello @blurymind!

Your suggestion is fantastic! It's good that I'm not the only one who thought Polygon2Ds are like DB meshes.

[blurymind]

Just thinking that there will be less code to maintain that way..

Polygon2D for now is slow on rendering, i think that this is bad idea.

[definite-d]

@Ranoller what node would you suggest for such a purpose?

[blurymind]

@definite-d if you want a 2d mesh deformation in your animation, only polygon2d can do it
http://docs.godotengine.org/en/3.1/tutorials/animation/2d_skeletons.html
However there seems to be a performance issue with it
godotengine/godot#19943
@sanja-sa basically created a new node and @Ranoller is already suggesting to use it - as it is more performant than polygon2d. But the dragonbones node lacks some basic features still when compared to its runtime and has only seen maintenance updates. It would be nice if somebody makes a pull to add these features to make it on par with godot's internal node

Hello!

Sorry to bother on this topic again, but this issue is quite a pain in my team's workflow. Certain anims require it, and now we're stuck between having to readapt the anims (which would eliminate the effects) and exporting to sprite frames (which would reserve the effects but would lead to a memory hog). Would a viable solution be to use the Frames feature of DB, or is this feature close to release? Please help.

[blurymind]

It's kind of why I don't use this runtime seriously atm. I really wish this feature was exposed to Godot

Well... this module is only changed to maintain compilation in godot master (in my branch) because original author doesn´t seem to be available. I only can guarantee compatibility with godot master if i don´t find a top-breaking change that i can not solve (not really c++ programmer)... so, probably not new features will be added.

For the moment i compile it in my system every x weeks to test with new godot changes and module compiles... i will try to maintain this compatibility until polygon internal vertices in godot can be animated and the polygon editor becomes more functional... before... well. This module can be droped out.
