In Unity, one of the first things that usually want to do is add some code so that I can move a 3D object with my keyboard keys. I found some ways after experimenting.<\/p>\n\n\n\n
On your object, also add the component Rigid Body<\/strong>. Then, create a new script, then drag it to your object so your object is using the script. Now, let’s change the code! My script name is ballchar, so just replace that to whatever you use.<\/p>\n\n\n\n One way to make the object move is to simply change the position of the object directly with transform<\/strong>. <\/p>\n\n\n Now you can move the objects position so it change x, y or z position in the direction of the keys you press down on the keyboard.<\/p>\n\n\n\n Another way to make the object move is to change the velocity on the objects Rigid Body<\/strong>. <\/p>\n\n\n Now you can move the objects velocity so it goes in the direction of the keys you press down on the keyboard! However, if we check the documentation it says this:<\/p>\n\n\n\n The better way I would say is to add a new component to your object called “CharacterController”, here you get some things for free such as the Move<\/strong> method.<\/p>\n\n\n\n Supplies the movement of a GameObject with an attached CharacterController component.<\/p>\n\n\n\n The\u00a0CharacterController.Move\u00a0motion moves the GameObject in the given direction. The given direction requires absolute movement delta values. A collision constrains the\u00a0Move\u00a0from taking place. The return,\u00a0CollisionFlags, indicates the direction of a collision: None, Sides, Above, and Below.\u00a0CharacterController.Move\u00a0does not use gravity.<\/p>\n<\/blockquote>\n\n\n Note that you might want to check under Rigidbody and Freeze Rotation to stop your objects from rotating.<\/p>\n","protected":false},"excerpt":{"rendered":" In Unity, one of the first things that usually want to do is add some code so that I can move a 3D object with my keyboard keys.
