Hello everyone!
In this video I will show you how to move a game object with arrow keys in Unity game. Here we have an empty project with a simple model of a ball which you can get from open gem art site. Here is a set of 3d objects which contains this ball. I’ll put a link to this asset into the description. Big thanks to the Ouren for this asset. Ok. Let’s quickly set up our project. First of all I create a floor for our ball. Create - 3D object - Plane. Here it is. Reset it’s position. And scale it down a bit. Here we go.

Next game object here will be a ball. I just D&D it into the hierarchy and bring it up like that. Our ball needs a couple of components. First one is a Rigidbody. And the second one is a sphere collider. Ok. Focus on the ball by double click. Collider is a bit too big and positioned not quite properly. Let’s fix it. I set center point position and radius. Almost there. Ok. Looking good for me. Now let’s put our main camera into proper position. Select it. I already know in what position I want camera to be so I set it here in inspector. And also I give the camera some rotation in X axis so game view will show us our playground this way.

Ok. To move our ball we will use a script named Move. Let’s take a look at it. It’s very simple. First we have a rigidbody reference to control it’s velocity. Then we have moveSpeed variable, dirX and dirZ variables that will help us to move our ball. In start method we set moveSpeed to 3 and get control over that rigidbody component. In update method we assign dirX and dirZ variables depending on which arrow button is pressed. So if we press left or right button then dirX becomes equal to negative one or positive one multiplied by moveSpeed. And if we press up or down button then dirZ becomes equal to negative one or positive one multiplied by moveSpeed. And in fixed update we pass a velocity to rigidbody by X and Z axis according to dirX and dirZ values. Velocity by Y axes stays the same. That’s the script. D&D this script to Ball game object.

That’s it. Now we can hit play and see how it works. I press left, right, up or down buttons and the ball moves according to that input. Hope this tutorial was useful for you. Thank you for watching. See you next time.
