LibGDX Matrix rotate single texture with 2 different origins in same frame
I want the box texture at first rotate 90 degree with origin (x1, y1) red dot, then rotate 45 degree with origin (x2, y2) blue dot.
Here is my code:
mx4.setToTranslation(x1, y1, 0);
mx4.rotate(0, 0, 1, 90);
mx4.translate(-x1, -y1); //Rotate 90 degree (this working)
mx4.translate(x2, y2);
mx4.rotate(0, 0, 1, 45); //Rotate 45 degree (not working, disappeared)
mx4.translate(-x2, -y2);
batch.setTransformMatrix(mx4);
batch.begin();
batch.draw(boxTexture, 0, 0);
batch.end();
My expecting result is like below:
Note: The circle is the texture that need to do 2 rotation with 2 different origins
But unfortunately it is not, the result is weird, the box texture disappears. The 90 degree rotation works fine, but 45 degree does not, any idea?
Thanks in advance.
