Making the player jump when the Space Bar is pressed Using a Rigidbody, it’s possible to make a character jump by applying an amount of upward force, allowing gravity to pull the player back down again.įor example, if I have a character, in this case a simple 2D box, with a Rigidbody and a Collider component attached to it, I can make the box jump by applying force to the Rigidbody when a jump button is pressed. To move the character under physics, I need to add a 2D Rigidbody, which allows it to be moved under physics simulation, and a 2D Collider, to stop it from falling through the floor. Meaning that it will be affected by gravity, it can be moved using physics forces and, when used with a Collider, it will collide into other objects that also have Collider components attached. The Rigidbody component in Unity allows an object to move under physics simulation. Or, when working with 2D physics, like this: Rigidbody2D.AddForce(Vector2 force) Like this, when working in 3D: Rigidbody.AddForce(Vector3 force)
This works by applying force to a Rigidbody component, using the Add Force method.
The basic method of jumping in Unity involves applying an amount of force to an object to move it into the air using physics.

How to increase jump speed in Unity (to prevent a floaty jump). How can you control the speed of the jump, to avoid floaty jumping physics?Īnd how can you limit how high the player can jump or let them jump higher by pressing the jump button for longer?Īnd exactly how you choose to make your player jump will depend on how your game works.īut don’t worry, because in this article I’ll show you everything you need to know about the basics of jumping in Unity, step by step, so that you can decide which method will work best for your game. However… it can be a surprisingly tricky thing to do right.īecause, to be able to make a player object jump in Unity, you’re going to need to decide how to move that object into the air.įor example, will you use physics to launch the player upwards, or will you use script-based movement to manually move the character up and down when they jump? Making a player jump in Unity seems like a very simple thing to do.
