POHow to gradually rotate an object to face another turning the shortest distance
text
Body
copied!<p>I'm currently trying to rotate a sprite depending on how many degrees(or rads, I prefer degrees) it differs from facing straight towards a target, the problem is when the target reaches a certain position the sprites decides to do rotate a full 360 to other way instead of doing the 10 extra. This picture probably explains the problem better:</p> <p><img src="https://i.stack.imgur.com/yUF9A.png" alt="Blue square = target, Red square = the object, green line = rotation it wants, black line = current rotation, brown arrow = how it rotates to achieve this, red arrow = how I want it to rotate."></p> <p>Blue square = target</p> <p>Red square = the object</p> <p>Green line = rotation it wants</p> <p>Black line = current rotation</p> <p>Brown arrow = how it rotates to achieve this</p> <p>Red arrow = how I want it to rotate.</p> <p>Note that Case 1 always work, depending what way it rotates, but Case 2 it always does that rotation, no matter if it is to the "right" or "left" of the current rotation.</p> <p>This is the code I'm using to rotate the object.</p> <pre><code> Vector2 distance = new Vector2(target.worldPos.X - this.worldPos.X, target.worldPos.Y - this.worldPos.Y); float wantRot = (float)Math.Atan2(distance.Y, distance.X); if (this.rotation < wantRot) this.rotation += MathHelper.ToRadians(45) * Time.deltaTime; if (this.rotation > wantRot) this.rotation -= MathHelper.ToRadians(45) * Time.deltaTime; </code></pre> <p>What i want to achieve is have it rotate (in Case 2) according to the red arrow instead of the brown one.</p> <p>NOTE: I'm not an expert at programming, I've only done it from time to time for the past year(Mainly simple 2D Shooter/shoot'em up kind of games), so in depth explanation would be appreciated. I'm also a student learning programming.</p> <p>PS: Suggestions for Title would also be appreciated as I had absolutely no idea what to put there.</p>
