So how do i rotate it like this? btw i don't like using affinetransform or graphics2d rotation. i was hoping for a better way. thanks java rotation 2d image rotation asked aug 11, 2012 at 2:09 36redsoxfan 2502515 1 btw i don't like using affinetransform or graphics2d rotation good luck then :p in java about the only way to do what you want with any level of efficiency is via affinetransform.
Java Libgdx Rotate 3d Object Following Mouse Stack Overflow Use context.translate to translate coordinates to the center of your player and then context.rotate to rotate the rectangle. to find the angle between the mouse position and the center of the player you can use math.atan2 function. Hello. i'm currently developing a top down game that involves rotating the player sprite to face the mouse's position. i am aware of the common trick: image angle = point direction(x,y,mouse x,mouse y); however this looks very choppy to me, and i would like to implement a smoothing feature. i. Using java to rotate an object to face the mouse: if you have ever used java's 2d api you probably have wanted to know how to make a character face your mouse. so you got on google and looked it up and guess what?. This class represents an affine object that rotates coordinates around an anchor point. this operation is equivalent to translating the coordinates so that the anchor point is at the origin (s1), then rotating them about the new origin (s2), and finally translating so that the intermediate origin is restored to the coordinates of the original anchor point (s3). for example, the matrix.

Hey guys, what i’m trying to do, in theory is take an object that is restricted to 2d space (z is 0 always) and i want to make that object rotate to face the mouse pointer, i’ve done this in flash and in c using opengl. i think the confusion i’m having is getting the position of the cursor in world space. Objects are always rotated around their relative position to the origin and positive numbers rotate objects in a clockwise direction. transformations apply to everything that happens after and subsequent calls to the function accumulates the effect. for example, calling rotate (half pi) and then rotate (half pi) is the same as rotate (pi).
