Rotating a grid,
Hey guys,
I made a base building game where you place your buildings on a grid. Now I created an AI that also builds a base and I want it to face the player with it's base. I can't just rotate the object, that leads to a lot of problems in my code.
How do I calculate the new position in a grid when immitating rotation? For 180° it works like: newX = gridSizeX - oldX and newY = gridSizeY - oldY. In the example image the grid the red cube is 0° and the blue cube is the new position after rotating by 90°, how do I calculate the new position? In some cases switching x and y works, in some cases I can leave x and just change y, it is very confusing. Please help!

,Hey guys,
I built a base building game using a grid to place objects on it. Now I made an AI to build objects as well. I want the AI to face the player with its castle. I can't just rotate the grids object, that leads to a ton of problems in my code. Is there a way to change the objects inside a grid to immitate rotating? In the example below the red cube is rotation 0°, the blue cube is rotation 90°. How do I calculate the new position?
With rotating 180° this is easy: newX = gridsize - oldX / newY = gridsize - oldY
But I can't get 90° and 270° to working. Sometimes leaving x and just changing y works, it's very confusing.
Please help.
