    <p>Problem: Upon spacebar press i need my projectile to fire and continue its life regardless of another press or letting go of the spacebar.</p> <p>below is both the code adding, updating, and drawing the projectiles. I have tried numerous reworkings of this code but alas am not experienced enough to have found a suitable solution yet.</p> <p>AddProjectile code below</p> <p>enter code here</p> <pre><code>//add projectile if spacebar is pressed private void AddProjectile(Vector2 position) { //i need somthing like this to make bullets autofire on phone //while (TouchPanel.IsGestureAvailable) //{ // Projectile projectile = new Projectile(); // projectile.Initialize(GraphicsDevice.Viewport, projectileTexture, position); // projectiles.Add(projectile); //} if (currentKeyboardState.IsKeyDown(Keys.Space) || currentGamePadState.Buttons.A == ButtonState.Pressed) { Projectile projectile = new Projectile(); projectile.Initialize(GraphicsDevice.Viewport, projectileTexture, position); projectiles.Add(projectile); } } </code></pre> <p>Update Projectile code below</p> <pre><code>private void UpdateProjectiles() { //update projectiles for (int i = projectiles.Count - 1; i &gt;= 0; i--) { if (currentKeyboardState.IsKeyDown(Keys.Space) || currentGamePadState.Buttons.A == ButtonState.Pressed) { //adds particle to first projectile but not again until the next fire butotn press //particleEngine.EmitterLocation = new Vector2(projectiles[i].Position.X, projectiles[i].Position.Y); projectiles[i].Update(); projectileOn = true; } //if projectiles not being fired remove them from the game screen else { projectiles.RemoveAt(i); } } } </code></pre> <p>the Draw method that draws projectiles to screen</p> <pre><code>//draw the projectiles //*********************************************************** //using the if here allows control of projectiles to pass... //...to the "currentstate of the spacebar (is pressed = fire) /***/ if (currentKeyboardState.IsKeyDown(Keys.Space) || currentGamePadState.Buttons.A == ButtonState.Pressed) { for (int i = 0; i &lt; projectiles.Count; i++) { projectiles[i].Draw(spriteBatch); } } //remove projectiles and reset if (currentKeyboardState.IsKeyUp(Keys.Space) || currentGamePadState.Buttons.A == ButtonState.Released) { UpdateProjectiles(); } </code></pre> <p>So, this is what i have so far and as stated can get the projectile to worl fine , i just cant get them to continue their life (until a collision or they reach the end of screen) once i let go of the keyboard spacebar.</p>

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.
