Look Modifier is commonly used to apply spine rotation and leaning effects. This is essential to make the character look around without Blend Trees.
Look Modifier.
Pitch Input: pitch or look-up angle in degrees.
Yaw Input: yaw or look-right-left angle in degrees.
Use Yaw As Delta: whether to accumulate yaw input every frame.
Use Yaw Turn Angle: whether to use the turn-in-place angle. Set this to true if is used.
Roll Input: roll or leaning angle in degrees.
Pitch/Yaw/Roll Offset Elements: bones that will be affected by rotation.
Use-cases
Look Modifier is generally used for any effects that require distributed spine rotation. It is quite common to bind player input values from the gameplay code to control rotation:
Using character controller value to drive the pitch input.
By default, Yaw Input is a world rotation value, which means you can bind the player's rotation directly to this property:
How to Look using player's global aiming rotation.
If there isn't a global rotation value, it is recommended to use the player's horizontal delta input instead:
How to Look using player's delta horizontal/yaw input.
Tip: using the player's delta input is easy to implement, but it doesn't give that much control as global rotation. For example, if we were to add look smoothing, we would use the global rotation variable instead.
Look angles are automatically adjusted to match the 90-degree target:
Auto-angle distribution.
Tip: Just type in the value, and the system will automatically compute the right angles for the rest of the list!
