Destroying blocks past 255

[Klem3n]

Does anyone know how to fix the bug where it only allows you to destroy blocks up to x and y of 255?

I know this is the problem: var pixel = new Uint8Array( 4 ); gl.readPixels( mx/gl.viewportWidth512, (1-my/gl.viewportHeight)512, 1, 1, gl.RGBA, gl.UNSIGNED_BYTE, pixel );

as its assigned to a byte array so the highest value is 255, I tried to change it to UNSIGNED_SHORT_4_4_4_4 and even a float with no luck. It kept returning 0,0,0,0 to the array

RESOLVED THE ISSUE:

SOLUTION: Find this in renderer.java: var whiteTexture = this.texWhite = gl.createTexture(); change parameter gl.UNSIGNED_BYTE of gl.texImage2D to gl.FLOAT

Then find: var bt = gl.createTexture(); and do the same for`gl.texImage2D`` under that

Then change var pixels = new UInt8Array... and the line under that to this.

to
var pixel = new Float32Array( 4 ); gl.readPixels( mx/gl.viewportWidth512, (1-my/gl.viewportHeight)512, 1, 1, gl.RGBA, gl.FLOAT, pixel );

And finnaly add this to beginning;

    var floatTextures = gl.getExtension('OES_texture_float');
    if (!floatTextures) {
        alert('no floating point texture support');
        return;
    }

change if ( pixel[0] != 255 ) to if ( pixel[0] != 1)

You seem to know what you're doing, do you have a way to increase the build height for multiplayer? I've been poking around render.js, world.js and blocks.js and can't seem to find the solution. I'm also not very good at programming, so that's another issue.

@Klem3n I am interested in your work on this. Would you mind sharing your code?
