rendering bitmapData

[L2L2L]

I'm trying to render a bitmap data multiple times. the code is very simple. I just do what I have to with the ctx property of the bitmap, this works when I just game.add[sprite|image](0,0,bitmapData); but is slow.

 

I try to use sprite.setTexture(bitmapData); or image.setTexture(bitmapData); but does not work.

I use img.loadTexture(bitmapData); to render the bitmapData; which is dynamic for it change with each iteration. But the out come is still slow... very slow. So this post is still up for assistance.

This is the recommended way to use a single bitmapData across many sprites: http://examples.phaser.io/_site/view_full.html?d=bitmapdata&f=cached+bitmapdata.js&t=cached%20bitmapdata

 

You could use loadTexture too, but it should only be done once, when the sprite is created. After that you just update the bitmapData itself and flag it as dirty.

thanks for responding, and the help. It work,,, but the dynamic created graphic that I will use from bitmapData is not rendering right. This graphic is a imageData that is create through canvas 2d render's methods. Do you have any suggestion for that.

 

What I'm doing:

 

1. Creating dynamic graphic with the bitmapData using it's property context.

2. take the image data off that canvas and altering the pixels

3. rendering the result to canvas through sprite aka display object.

 

the result is blur... if that help.

 

Thanks again for the help.

I only partly follow what you mean... are you using 1 bitmapData for the blur effect, and then another for the Sprite textures? Or just 1 bitmapData with the whole blur effect on it for all sprites?

 

Showing some simplified / cut-down code would help

Is possible to get many sprites with different textures using only one bitmapdata instance?

I think the fastest way I have found so far is :

myBitMapDataObject.add(mySprite);

What does this code mean?
