so first off I want to say that I am new to using AffineTranslation and Graphics2D’s translate function. So I am sorry if my question is unclear! I sadly don’t know how to word the question.

What I am trying to achieve: I want to have a camera that follows the player and I also want an AffineTransform that controls the rotation of the player. So I basically want a classic camera combined with the ability to rotate the player using the ‘D’ and ‘A’ buttons. An example of this "rotation":

This is taken out of my game and the rotation works as intended. However when I tried adding a camera that follows the player something weird happened. This is the code inside my paintComponent class:

public void paintComponent(Graphics g) {             Graphics2D g2d = (Graphics2D) g;     super.paintComponent(g2d);               g2d.translate(playerCam.getX(), playerCam.getY());     //Set font     g2d.setFont(pixelFont_reg);     //     AffineTransform backup = g2d.getTransform();          AffineTransform a = AffineTransform.getRotateInstance(player.getRotation(),player.getX() + (player.getWidth() / 2),player.getY() + (player.getHeight() / 2));                //Paint grid of grass as a test of Assets class     for(Tile tile : tiles) {          tile.drawTile(g2d);          }                                        //Rotate player depending on rotation var     g2d.transform(a);          player.drawEntity(g2d);               //Stop rotating player     g2d.setTransform(backup);      g2d.translate(-playerCam.getX(), -playerCam.getY());          //Draw Font     g2d.setColor(Color.white);     g2d.drawString("FPS: " + Integer.toString(GameLoop.frameRate), 10, 40);     //End of Draw Font                } 

This code didn’t affect the player at all. It only affected the tiles and the text I had displayed? I predict that my AffineTransform that handles the rotation has something to do with it but I have no clue on why? Does anyone have a solution to this issue? I searched the web but because I didn’t know how to word the issue it resulted in zero results.

You can see the issue here.

Thanks!

Any help is appreciated!
