LookAt rotate around X
I know this has been asked and answered a million times , mostly relating to y rotation for turrets etc. but.....
I am trying to make a Cube (1) Rotate around its X Axis only. To look at another Cube object (creating a Flap ). Local Z is facing forward correctly ,Y is Up. Using below simple code, Cube (1) snaps to look at World Z
targetPostition = new Vector3 ( transform.position.x, target.position.y, target.position.z );
transform.LookAt(targetPostition);
If I set it to :
... new Vector3 ( target.position.x, **transform.position.y**, target.position.z );
Cube(1) stays facing forward in local position and rotates perfectly around Y only, but I need to rotate around X.
I have been through tons of answers here and elsewhere , have also tried using Quaternion.LookRotation , but again with .x restricted to transform.position . Cube(1) looks towards World Z only.
Im well and truly stuck here, any suggestions greatly appreciated
private void Update()
{
targetPosition = transform.position + (Vector3.ProjectOnPlane(Target.position - transform.position, transform.right));
transform.LookAt(targetPosition);
}
This will keep the rotation of the object on its Y and Z intact while rotating the object along its X axis.
NOTE: targetPosition apologies for my mis spelling !
Thank you very much for replying This only seems to work if the target cube is moved into a position so that Cube(1) is again looking in World Z direction.
ProjectOnPlane () has fried my brain , especially after spending all day frustrated with what i though would be a simple process.
i just want to rotate the long cube like a wing flap around x only ( will be making target a grabbable object in XR Interaction.
If there is a more suitable solution please let me know .
Thanks everyone ))
I've updated the script and fixed an issue when the object wasn't at the origin, I hope it will fix the issue you're having.
The LookAt method is meant to align the Z axis towards the target position.
Fantastic. That works perfectly. I hate to just paste stuff in without knowing how it works , but now i can get over this hurdle and onto the next one.
Thank you ever so much for your help
