3D Platformer GameDev Series – Weekly Blog #20: Adding Enemies (Part 3)

Hey everyone! I apologize as it’s been nearly a month since my last blog post – I have simply been preoccupied with things other than game development. But, the important thing is that I still intend on completing the 3D platformer course by the end of this year. As 2020 unwinds, I have to put a bit more of my spare time into the course over the next few months. With that, let’s jump right into Unity and continue where we left off with our enemy skeleton.

After setting up the AI states for the enemy skeleton earlier, one final thing that needs to be done is to return the enemy skeleton to its patrolling state when it’s in the attacking or chasing state and the player is no longer within attacking or chasing range:

Behold, the fully-implemented AI states of our enemy skeleton in the game:

Next, we will create a hitbox for the enemy skeleton’s attack. A hitbox is an invisible, defined area whereby damage is incurred. In this case, a damage hitbox is added and activated in the skeleton’s attack animation (as soon as the skeleton begins to attack) and deactivated when the skeleton completes its attack. If the player is inside the hitbox, damage is done to the player (via the “Hurt Player” script which was created earlier when the player health system was implemented):

Let’s now see the skeleton’s attack causing damage to our player in the game:

That’s it for this week’s blog! I hope you enjoyed the read. Next time, we will implement a way to allow the player to kill the enemy skeleton. It wouldn’t really be fair otherwise, right? 😉 Upon killing the skeleton, this would further spawn coins for the player to collect! Stay tuned!
