3D y rotation

sionco

Hi, I'm trying to rotate a 3D object with the left and right keys along the y axis. However, it only rotates about 180 degrees each way before it won't rotate any more unless I press the opposite key. If I change the axis to the z or x it works fine and keeps rotating

if(Input.is_action_pressed("ui_left")): rot=1 if(Input.is_action_pressed("ui_right")): rot=-1 var rotat = get_rotation() rotat.y += ( rotdelta) set_rotation(rotat) var t = get_transform() t.origin -= t.basis[2](velocity.z*delta) set_transform(t)

Thanks for your help

Anyone?

I'm not sure what you want. But you can try this (not tested)

const ANGLE_INC = 20 if(Input.is_action_pressed("ui_left")): angle += deg2rad(ANGLE_INC) if(Input.is_action_pressed("ui_right")): angle -= deg2rad(ANGLE_INC) var rot = Quat(Vector3(0, 1, 0), angle) var t = get_transform() set_transform(Transform(rot, t.origin))

I want the object to keep rotating round and round if I hold the left or right arrow keys down, and not stop half-way.

I used the code from the Kinematic 3D demo and added these 2 lines under the inputs. Should rotate on Y only, as long as the key is held down.     if Input.is_action_pressed("turn_left"):         rotate(Vector3(0, 1, 0), deg2rad(10 ROT_SPEED))     if Input.is_action_pressed("turn_right"):         rotate(Vector3(0, 1, 0), deg2rad(-10 ROT_SPEED))

Thanks Ghost, that's brilliant!
