how to make Pixi.Spritesheet compatible with Rpg maker mz

[nio_kasgami]

Hi, 

I love a lots the implementation of Spritesheet since it work like atlas and for UI it's wonderful to use or any project who has a lots of Sprites. 

Although the way that MZ or rpg maker implements sprite seem to be a puzzle I can seem to figure out to implement Spritesheet. 

Here's the SPrite API source code : 

https://developer.rpgmakerweb.com/rpg-maker-mz/Sprite.js.html#line9 

It seem to be working through Bitmap (which is common with RM) instance instead of a direct texture so figuring out how to implement it 

here's the Bitmap class API source code : 

https://developer.rpgmakerweb.com/rpg-maker-mz/Bitmap.js.html#line9

 

My guess was to go and Set the base texture / image to point towards the Spritesheet but I am unsure if it would not work? my guess would be also to create an instance of Spritesheet inside the bitmap class but it seem that would actually cause a memory leak (creating instance duplicates) 

so I am kinda at lost there?

put spritesheet baseTexture to bitmap

sprite.bitmap = myBitmap

sprite.texture = oneOfSpriteSheetTextures
sprite._frame = oneOfSpriteSheetTextures.frame

something like this should work

@ivan.popelyshev Thanks! so if I understand MyBitmap is being the new Bitmap()? I am unsure (sorry if I am dumb)

I honestly didnt try it yet. In theory, if you put baseTexture into bitmap, this has to work. 

I thought that RM author will rewrite Bitmap when we added new functions in pixi-v5 specially for that, well, its not the case

I see well that's the thing 

they didn't rewrite much and didn't inputed that. 

I will do some test  so if I understand what u say

the code should look like this : 

var spritesheet = SpriteSheet["MySprite"]; // Let's assume it was loaded before hand

var sprite = new Sprite();

sprite.bitmap.basetexture = spritesheet.basetexture;
sprite.texture = spritesheet.texture;
sprite._frame = spritesheet.frame;

I aint sure ill try to write an Atlas wrapper so it automatically setup those things. but yeah if I understand correctly it's how you would approach it?

"spritesheet.texture.frame" not "spritesheet.frame"

Yes. I would do it and debug the result.

In case you use trimming or rotations in spritesheet, try "texture.orig" instead of frame.

okay okay ill test it tonight
