    <p>i wanna move a point (Vector2) on an angle. i have my angle. but i'm not good in math or libgdx. for getting angle i use this : </p> <pre><code>degrees = (float) ((Math.atan2(touchPoint.x - x, -(touchPoint.y - y)) * 180.0d / Math.PI) + 240.0f); </code></pre> <p>now, i want to move vector. but i really don't know what i must do... i looked at questions but there was just somethings about changing angle, not transfer. i think there must be a function for this in libgdx. please help.</p> <p>UPDATE :</p> <pre><code>public class Games implements ApplicationListener { SpriteBatch spriteBatch; Texture texture; float x = 160; float y = 5; Vector2 touch; Vector2 movement; Vector2 position; Vector2 dir; Vector2 velocity; float speed; float deltaTime; @Override public void create() { spriteBatch = new SpriteBatch(); texture = new Texture(Gdx.files.internal("images/1.png")); touch = new Vector2(); movement = new Vector2(); position = new Vector2(); dir = new Vector2(); velocity = new Vector2(); speed = 5; deltaTime = Gdx.graphics.getDeltaTime(); } public void render() { Gdx.gl.glClear(Gdx.gl10.GL_COLOR_BUFFER_BIT); deltaTime += 0.5f; spriteBatch.begin(); begin(deltaTime); spriteBatch.draw(texture, position.x, position.y); spriteBatch.end(); } private void begin(float deltaTime) { touch.set(Gdx.input.getX(), Gdx.input.getY()); position.set(x, y); dir.set(touch).sub(position).nor(); velocity.set(dir).scl(speed); movement.set(velocity).scl(deltaTime); position.add(movement); } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
