[Solved] Slick 2D Game Scaling and Rotating Problems

The rectangle in the minimap still perpetuates the “camera” idea. Imagine the minimap rectangle is stuck in the center of the minimap, and the entire map scrolls to fit the visible part within that rectangle. That’s how the camera works: your camera never moves, you simply move the whole world into view.

Then you will see that it is not the spoon that bends, but yourself

Yes thats how the OP is currently doing it, right? Translate everything in the entire world. But the idea posed in the thread is to not move the entire world but to move the camera rectangle. The latter matches the minimap example.

Another way of thinking about it is you move the minimap rectangle internally, but to actually render things into view you translate (move) it and the world back in the reverse direction so it’s back at the center where your fixed unmoving camera lives.

In that case, the camera, such as it is, is like any other object in the world, except you always render it first and you use the inverse of the normal translation and rotation to get your camera transform on the world.
