Struct LockedAxes 

pub struct LockedAxes(/* private fields */);

Flags that lock specific movement axes to prevent translation or rotation.

Use this to constrain body movement to specific directions/axes. Common uses:

• 2D games in 3D: Lock Z translation and X/Y rotation to keep everything in the XY plane
• Upright characters: Lock rotations to prevent tipping over
• Sliding objects: Lock rotation while allowing translation
• Spinning objects: Lock translation while allowing rotation

Example

// Character that can't tip over (rotation locked, but can move)
body.set_locked_axes(LockedAxes::ROTATION_LOCKED, true);

// Object that slides but doesn't rotate
body.set_locked_axes(LockedAxes::ROTATION_LOCKED, true);

// 2D game in 3D engine (lock Z movement and X/Y rotation)
body.set_locked_axes(
    LockedAxes::TRANSLATION_LOCKED_Z |
    LockedAxes::ROTATION_LOCKED_X |
    LockedAxes::ROTATION_LOCKED_Y,
    true
);

Get the underlying bits value.

The returned value is exactly the bits set in this flags value.

Convert from a bits value exactly.

pub fn from_name(name: &str) -> Option<Self>

pub fn insert(&mut self, other: Self)

The bitwise or (|) of the bits in two flags values.

pub fn remove(&mut self, other: Self)

The intersection of a source flags value with the complement of a target flags value (&!).

This method is not equivalent to self & !other when other has unknown bits set. remove won’t truncate other, but the ! operator will.

pub fn toggle(&mut self, other: Self)

The bitwise exclusive-or (^) of the bits in two flags values.

pub fn set(&mut self, other: Self, value: bool)

Call insert when value is true or remove when value is false.

The bitwise or (|) of the bits in two flags values.

pub const fn difference(self, other: Self) -> Self

The intersection of a source flags value with the complement of a target flags value (&!).

The bitwise exclusive-or (^) of the bits in two flags values.

pub const fn complement(self) -> Self

The bitwise negation (!) of the bits in a flags value, truncating the result.

impl LockedAxes

pub const fn iter(&self) -> Iter<LockedAxes>

Yield a set of contained flags values.

Each yielded flags value will correspond to a defined named flag. Any unknown bits will be yielded together as a final flags value.

pub const fn iter_names(&self) -> IterNames<LockedAxes>

Yield a set of contained named flags values.

This method is like iter, except only yields bits in contained named flags. Any unknown bits, or bits not corresponding to a contained flag will not be yielded.
