Previously

In Part 3 we made an Enemy, a Health Bar, and a shooting Gun. So, today we are going to make an obstacle for our Enemy and make an Enemy which shoots our Player.

Step 1. Obstacle for our Enemy

Making an obstacle for our Enemy is very important. This is a must when you want to create a map. To create it:

  1. Add a new object
  2. Select Tiled Sprite
  3. Name it "Wall"
  4. Select Wall_1.png
  5. Go to the Behavior tab
  6. Click on Add a new behavior
  7. Select Pathfinding Obstacle
  8. Click on OK
  9. Now, right-click on the Wall
  10. Click on duplicate
  11. Rename it Wall 2
  12. Now double click on it to open Object Editor
  13. Right-click over the frame and click on delete to delete the frame
  14. Now click on Add
  15. Select Wall 2 1 asset
  16. Click on OK
  17. Now drag it over the scene

We have made two different walls now we net to keep it as a group. To do that:

  1. Open the Group Editor (If not opened)
  2. Click on Add a new group
  3. Name the group Wall
  4. Double click on Wall to open group Editor
  5. In the Object name right Wall 1 and click on the Enter key
  6. Do the same by writing wall 2

Now, we have our obstacle for the Enemy. But, we also don't want Player to pass through things that the Enemy can't. To do that:

  1. Add a new action
  2. Select Player
  3. Select Separate objects
  4. Choose Wall
  5. Click on OK.

Step 2. Animate our Player

We know that our Player has 2 animations. But only the first one is Played. We want the second one to play when the Player is moving. And to do so:

  1. Go to the Events tab
  2. Add a new Event
  3. Add a new condition
  4. Select Player
  5. Select Is moving
  6. Click on OK
  7. Now, add a new action
  8. Select Player
  9. Select Change the animation
  10. Choose = as the operator sign
  11. Write 1 in the value
  12. Click on OK

Now the animation changes when we move but doesn't change to 1 when we stop. To do that:

  1. Add a new Event
  2. Add a new condition
  3. Select Player
  4. Select Is moving
  5. Now, click on OK
  6. After that hover over that condition and use the right mouse button
  7. Click on Invert Condition
  8. Now add a new action
  9. Select Player
  10. Choose = as the operator sign
  11. Write 0 in the value
  12. Click on OK

Step 3. Optimize for better performance

We need to optimize our game for a better performance. To do that, we can delete unnecessary objects like Bullet. When we miss our target, we have to make sure that the Bullet doesn't just keep going and going, it should be deleted. To do that we have a Behavior called Destroy Outside the Screen. To use that:

  1. Double click on Bullet to open the Object Editor
  2. Go to the Behavior tab
  3. Click on Add a new Behavior
  4. Select Destroy Outside the Screen
  5. Click on OK

In this part, We learned how to Optimize our game for better Performance. We also learned how to animate a sprite and make an obstacle for our Enemy.
