press key, rotate around something
hi, I want to simply rotate object on Z-axis 59 degrees if A-button is clicked,
if ( Input.GetKeyDown( "space" ) ) {
transform.RotateAround(Vector3.zero, Vector3.right, 150);
}
but rotate function description says, Eular Angles. when I saw huge I article on Eular angles on wikipedia I hid beneath the table hoping it would go away :S
is there a converter or some simpler tutorial explaining eular angles or unity function that uses normal angles ?
oh and btw whats key kode for A-button? unity reference said A <-, but this gives me error so i'm stuck with space ;|
Here: Try this script - it should solve all your problems:
var rotation = 1.0;
function Update () { if (Input.GetKey ("a")) { rotation += 0.2; transform.Rotate (0,0,rotation * Time.deltaTime); } }
The snippet of code above smoothly rotates the cube. If you just want it to 'go', remove the rotation += 0.2 line.To change the rotation speed, modify the 0.2 number. Hope this helps! Also, here's a link to the input page for all the keys in Unity.
P.S. Hiding under beds is much safer, and you should always ask all your Unity-related questions here. :)
Your code was framerate-dependent, and also defining rotation as an int means that adding 0.2 to it would cause it to never increase, so I fixed it.
@Eric5h5: Thanks a lot. I didn't think of that - I'm still a beginner in the logic of coding. Although I know the API, I keep forgetting those $$anonymous$$ute details that make things go.
