[Solved] PIXI.Container negative coordinates not taken in account

[Feelzor]

Hello !

I have a PIXI.Container supposed to fill the whole screen, but if you zoom out the screen with, for example, SRD's plugin, or use the shake function, it happens that it won't fit the whole screen. I found a solution for that, but there is a problem : when using this.position.set(x, y) with x and y being negative, the PIXI.Container won't move an inch, it will just stay at the same position.

I tried to put positive coordinates to make sure the problem didn't come from the position not taken in account, and the Container moved just as intended. So the problem really comes from coordinates.

What happens is that the (0,0) position is not the top left corner of the screen if you have a map wide enough and a scale between 0 and 1 exclusive.

So my question is how to make the Container take negative coordinates to move it to the left, or is there a way to say to the container to start at the top left corner of the map? (like the top left corner of the case in (0,0).

Thanks for your time and your answer ^^

EDIT: Here's the code :

Spriteset_Map.prototype.createLighting = function() {
    $gameLighting.clear();
    this._lightingTexture = PIXI.RenderTexture.create(LightingSurface.getRecommendedWidth(), LightingSurface.getRecommendedHeight());
    this._lightingSurface = new LightingSurface();
    this._lightingSprite = new PIXI.Sprite();
    this._lightingSprite.texture = this._lightingTexture;
    this._lightingSprite.blendMode = PIXI.BLEND_MODES.MULTIPLY;
    this._lightingSprite.alpha = 1.0;
    this.addChild(this._lightingSprite);
};

Spriteset_Map.prototype.updateLighting = function() {
    this._lightingSurface.update();
    Graphics._renderer.render(this._lightingSurface, this._lightingTexture, false);
};

function LightingSurface() {
    this.initialize.apply(this, arguments);
}

LightingSurface.prototype = Object.create(PIXI.Container.prototype);
LightingSurface.prototype.constructor = LightingSurface;

LightingSurface.getRecommendedWidth = function() {
    var scale = 1 / $gameScreen.zoomScale();
    return Graphics.width * (scale + 0.5);
};

LightingSurface.getRecommendedHeight = function() {
    var scale = 1 / $gameScreen.zoomScale();
    return Graphics.height * (scale + 0.5);
};

LightingSurface.prototype.initialize = function() {
    PIXI.Container.call(this);
    this._width = LightingSurface.getRecommendedWidth();
    this._height = LightingSurface.getRecommendedHeight();
    this.position.set(Graphics.width - this._width / 2, 0);
    this._createSurface();
};

LightingSurface.prototype._createSurface = function() {
    this._surface = new Sprite(); // This is the part that is misplaced, I guess
    this._surface.bitmap = new Bitmap(this._width, this._height);
    var color = GameEditor.rgbToHex($gameTime.tint(0), $gameTime.tint(1), $gameTime.tint(2));
    this._lastColor = color;
    this._surface.bitmap.fillAll(color);
    this.addChild(this._surface);
};

plz give code, you cannot get help without your code.
Container can move with negative value, so you maybe do something wrong.

I updated the first post with the code I use ^^

EDIT : The problem seems to come from SRD's plugin, because when I move the sprite, it actually moves but there is a margin on the top left. So the problem is solved.
