Collections; using System. Sets the rotation of the constrained GameObject to the source GameObjects. Is there a way to constrain a rigidbody’s position and rotation in local space? I couldn’t find an answer with Google, just a lot of other people asking the same question. What it does extra is keep the local up-axis local, and you can see a very clumsy demonstration The constraint calculates rotation toward each target to produce a weighted sum. Player click: Immediately flap upwards When going up (flap): Rotate upwards, to a certain extent When falling: Rotate downwards, to a certain extent Only way I can think of to do the rotation is to: set the angularVelocity clockwise/counter clockwise, depending on velocity. x, transform. Annotations; using System. Disable an axis to stop the Constraint from controlling it, which allows you to edit, animate, or script it. eulerAngles. It’s resting rotation is: (-100, -50, 10); these rotation values are all taken from the inspector. Here is the script I have on my character: using System. 12f1 HDRP 7. constraints. Rotation Offset: The X, Y, and Z rotation offset from the Transform that the Constraint imposes. Tip Rotation Weight: The weight of the rotation applied to the Tip. (this will constrain the rotation to a single local axis) And then use transform. weight: The weight of the constraint component. InverseTransformPoint() to bring the target Vector3 into local space coords, so that you can zero out the y axis relative to the rotating part. This is the same as the freeze rotation option.
