Previously

In Part 1, we made our Player and moved it. Today, we are going to make a Gun and aim it towards the mouse. We are also going to make a Camera follow our Player.

Step 1. Add an object

Now that we are going to make a Gun, we need to do this: Add an object Choose Sprite Name it "Gun" We have made our Gun. Now we need to make specify its centre. A centre is a point from where an object rotates.

  1. Double click the Gun to open Object Editor.
  2. Click on Add animation
  3. Click on Add
  4. Select "Gun 1.png"
  5. Select OK
  6. Click on Edit points
  7. Click on Edit button of the centre point
  8. Write 4 in X and 3 in Y
  9. Click on Close
  10. Click on Apply

Now, we have specified our Centre of sprite we can now move on.

Step 2. Keep gun around player

We have created our Gun. Now, we should stick our Gun with Player. To do it:

  1. Go to the Events tab of the scene
  2. Click on Add a New Event
  3. Click on Add action
  4. Here you will have a list of your objects. Select Gun.
  5. Now, a new box appears. Here, you have the list of actions.
  6. Search for Position
  7. After finding, select Position
  8. A new box appears.
  9. In the X position textbox, write Player.PointX("Center") and in the Y position textbox, write Player.PointY("Center").
  10. Give both modification signs a sign of "=".
  11. Click on OK.

Now, the gun follows the Player or we can say it sticks to the Player.

Step 3. Aim towards mouse

It cannot be called a shooter game if we don't know how to aim. So to aim:

  1. Add a new action
  2. Select Gun
  3. Search for Rotate towards Position and click it
  4. In the X position textbox, write MouseX()
  5. In the Y position textbox, write MouseY()
  6. Click on OK

Step 4. Shoot

If we want to shoot, we need a bullet. So let's make a bullet:

  1. Click on Add a new object
  2. Select Sprite
  3. Name it "Bullet"
  4. Click on Add a new animation
  5. Click on Add
  6. Select "Bullet-1.png" asset
  7. Click on Apply

So we have made a Bullet sprite. But that's not enough. We also need to specify from where does the Bullet appears. And for that, we need a point in our Gun. To make a point:

  1. Double click on Gun
  2. Click on Edit Point
  3. Click on Add a new point
  4. Name the point "Bullet"
  5. Change its X position to 14 and Y position to 2.
  6. Click on Close
  7. Click on Apply

Now we need to shoot it. To shoot:

  1. Go to the Events tab
  2. Add a new event
  3. Add a new action
  4. Select Bullet
  5. Select Create a new object
  6. In X position textbox, write Player.PointX("Bullet")
  7. In Y position textbox, write Player.PointY("Bullet")
  8. Click OK
  9. Now, add a new condition
  10. Search for Mouse button pressed or touch held
  11. Select it
  12. Choose the mouse button you want the Player to press for shooting
  13. Click OK

Now, we can shoot while we click.

Step 4. Following camera towards player

If we have a big map and want the Player to explore, we want the Camera to follow Player. So, we need to do this:

  1. Add a new action
  2. Search for Camera
  3. Select Centre the camera on an object
  4. In the Object textbox, select Player
  5. Click on OK

Step 5. Preview your game

To preview your game, click on the Preview button in the toolbar. We can now see that our Gun rotates towards the mouse. If we move our Player, it moves but we don't feel like it. That's because we don't have anything other than the Player to give us the sensation of movement.

Conclusion

In this part, we created a Gun which aims towards the mouse. We also made our Camera follow our Player. In Part 3, we will be creating a Health Bar for our Player.
