        shader.prepareTexture(tex, Tint.combine(fillColor, tint));
        shader.addQuad(topTransform(), x, y, x + width, y + height, 0, 0, 1, 1);
    }
    return this;

Example 2 with Tint

use of playn.core.Tint in project playn by threerings.

the class AbstractSurfaceGL method drawLine.

@Override

    bindFramebuffer();
    // swap the line end points if x1 is less than x0

    }
    float dx = x1 - x0, dy = y1 - y0;
    float length = FloatMath.sqrt(dx * dx + dy * dy);
    float wx = dx * (width / 2) / length;
    float wy = dy * (width / 2) / length;
    InternalTransform l = ctx.createTransform();
    l.setRotation(FloatMath.atan2(dy, dx));
    l.setTranslation(x0 + wy, y0 - wx);
    l.preConcatenate(topTransform());
    GLShader shader = ctx.quadShader(this.shader);

        shader.addQuad(l, 0, 0, length, width, 0, 0, 1, 1);
    }
    return this;

    this.tint = (ialpha << 24) | (tint & 0xFFFFFF);
    return this;
