What will happen if the condition is met? — Ever thought about why a menu only opens up if you press the, let’s say, ESC key on your keyboard? Or the menu button on your controller? Why does the player only attack when you press X on your controller and only jumps when you press the A button on…

Moving in a circle does not have to be coded, ya know? — We already created a circular movement behavior with the help of math. But you know what? I don’t like math… Like, at all. And hey, it’s okay to hate it, even as a game developer where you need it sometimes. Anyways, let’s create a circular movement today without using math…

Hmm… Which enemy will be the right one to destroy? — There might be some time when you develop a game where you need to calculate the closest enemy out of all on the screen.

Wanna play cat and mouse? — Another horrible pun to start the article. Nice! Anyways, you might have played some games where some objects are always looking at the mouse pointer.

Player. Where are you? I need some fresh flesh… — Okay, no worries. We have a screen between us, so nothing will happen to you ;-) Anyways. You might have played some games before in which enemies are chasing you. Take Minecraft as an example. Remember the zombies chasing you at night? Or, to turn the paper around, games allowing…

Keep an eye on a GameObject with LookRotation! — You might have played a Tower Defense game before. Have you ever noticed that at least one enemy is always looking at you, regardless where you move to? Exactly that is the concept of LookRotation in Unity. It keeps track of another GameObject and rotates to always focus it. Let’s…

Moving in straight lines? - BORING! — Movement in games is exciting. No, really. I’m not kidding. It just a question of how you let the player (or the enemy) move. Let’s say you have an enemy which randomly decides to approach you in a circular way instead of in a straight line. Exciting, huh? Now then…

Fall down with your own gravity style! — Ever played a game with a trap door which let’s you conveniently fall down and you can’t do anything about it? Lucky you, then! Today’s challenge is kind of the same. Let’s take a look at it!
