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. Add objects and set it up

Today, we are going to make an Enemy so, we need to make an object for it. So, let's add it:

  1. Click on Add a new object
  2. Click on the Sprite
  3. Name it "Enemy damager"

Now, we need to add assets to our object. To do so:

  1. Double click on Enemy
  2. Click on Add a new animation
  3. Click on Add
  4. Choose "Enemy damager-1.png" asset
  5. Click on OK
  6. Drag it on the scene and place it around Player

Step 2. Set its destination

We have made an Enemy object and gave it a Behavior, but that's not enough. We need to give it a destination too. And to give it a destination:

  • Go to the Events tab
  • Make a new event.
  • Add an action
  • Select Enemy
  • Select Move to a position
  • In the X position textbox, write Player.X(), and in the Y position textbox, write Player.Y()

Note

You should use Pathfinding behavior if you have a map and you want the AI to differentiate between obstacles, destination, and something we want them to ignore.

Step 3. Damage Player

Now, we will be damaging our Player. I want to damage the Player whenever the Enemy touches the Player. Previously, we learned how to make a Health Bar for our Player. Health Bar uses Health variable to show health, so if we want to damage Player, we should reduce Health. To reduce Health:

  1. Add a new event
  2. Add a new action
  3. Select Player
  4. Select Value of an object variable
  5. Here, you will get a list of variables you made of the selected object
  6. You can see Health too. Click on it.
  7. Choose the Operator sign "-"
  8. In the value, write the amount of health you want the Player to lose. Here, I will write 5.
  9. Click on OK

So we have learned how to damage our Player. But, to damage the Player whenever Enemy touches him, we need to do this:

  1. In the same previous Event, add a condition
  2. Select Enemy
  3. Select Collision
  4. Now, select Player
  5. Click on OK

But this will damage our Player rapidly, so let's delete Enemy whenever it collides. To do this:

  1. In the same Event, add an action
  2. Select Enemy
  3. Select Delete Object
  4. Click OK

Step 4. Previewing the game

While Previewing the game, you can see that the Enemy damages our Player. And whenever it does, it disappears.

Conclusion

In this part, we created an Enemy which can damage our Player. In Part 5, we will be making a map. We will also be animating our Player and learning how to optimize our game for a better experience.
