The second parameter is Connected Rigid Body. In this case, you don’t want this to happen, so leave it unchecked. This determines whether or not the two objects connected by the joint can collide with each other.
The Distance Joint 2D’s first parameter is Collide Connected. Turn your attention back the component in the Inspector. The rocking behavior is the actual joint behavior, but what’s the deal with the initial jolt of energy? This is actual expected behavior and you’ll learn about it soon. Right away, you’ll notice that the Hexagon flies across the screen until it stops near the origin point, then begins to rock back and forth on the joint. Run the scene, keeping your eye on the Hexagon. You’ll notice that once you have the component attached to the Hexagon that a green line extends from the Hexagon to the center of the screen. Select Hexagon_Djoint in the Hierarchy and add a Distance Joint 2D Component to it, as shown below:Īs you can see in the following image, this new component has several parameters that you can adjust to produce the best result for your game:įear not - you’ll soon learn what all these these parameters do and how you can adjust them.
You’ll test this out on the red square and blue hexagon in the upper left of the scene. The first joint you’ll add – the Distance Joint 2D – has a very basic goal: to keep two objects separated by a constant distance. It’s time to get these objects working together with joints! Distance Joint 2D

For best results, put your Game view in Free Aspect mode and adjust its size in the Unity GUI until the objects and labels appear similar to the above image.

While most of my ideas in the examples are sports based, I am sure there are other potential ideas on how to make a course dedicated to Unity physics of objects that can be more generalized for other genres.Note: While the labels in this scene are in fixed positions, the movement of the objects is based on the size of your Game view. Players objective is to get around the defender, and score a goal) 1 AI defender that only tries to steal the ball from you. Mini Soccer game (1 AI goalie that follows the ball but stays in the net.Just Tap It In (Player is a putter, and the player must whack the ball to a target).Curling / Shuffleboard (Control the aim and power an object has, and try to slide it onto a target).Target Practice (Throw / Kick a ball into a target that breaks when it hits it).3D Pong (A classic game of Pong but on a 3D Scale).Mini Project Ideas for this could probably include: Object only moves if it is touching a player hitbox while pressing a hotkey.Longer the hotkey is pressed the more velocity is added when hotkey is released.Add velocity or force to an object if the object is pressing a hotkey.Add velocity or force to an object when the object touches another object.Make an object break when enough force runs into it.Make an object slide but slow down like a hockey puck on ice.Make an object bounce like a Soccer or Tennis ball.Some things I would like to learn for a course like this would be: Some examples of popular games that rely on physics include Rocket League, Portal (1 & 2), Fall Guys, and Golf With Your Friends (or Golf It). I imagine students that are interested in making 3D based games in Unity would enjoy a course that explains in detail how to make objects move, stop, float, or even break apart.
However, so far I haven’t seen a course dedicated for Unity that goes from the basics to intermediate. A game genre I have been interested in making for a while is Sports games, particularly ones that involve a ball like Tennis or a puck like Ice Hockey.
