Character bodies are special types of bodies that are meant to be user-controlled. They are not affected by physics at all; to other types of bodies, such as a rigid body, these are the same as a [AnimatableBody3D]. However, they have two main uses:
|
|
[b]Kinematic characters:[/b] Character bodies have an API for moving objects with walls and slopes detection ([method move_and_slide] method), in addition to collision detection (also done with [method PhysicsBody3D.move_and_collide]). This makes them really useful to implement characters that move in specific ways and collide with the world, but don't require advanced physics.
|
|
[b]Kinematic motion:[/b] Character bodies can also be used for kinematic motion (same functionality as [AnimatableBody3D]), which allows them to be moved by code and push other bodies on their path.

<description>
|

Returns a [KinematicCollision3D], which contains information about a collision that occurred during the last call to [method move_and_slide]. Since the body can collide several times in a single call to [method move_and_slide], you must specify the index of the collision in the range 0 to ([method get_slide_collision_count] - 1).

|
|
Moves the body based on [member motion_velocity]. If the body collides with another, it will slide along the other body rather than stop immediately. If the other body is a [CharacterBody3D] or [RigidDynamicBody3D], it will also be affected by the motion of the other body. You can use this to make moving and rotating platforms, or to make nodes push other nodes.
|
|
This method should be used in [method Node._physics_process] (or in a method called by [method Node._physics_process]), as it uses the physics step's [code]delta[/code] value automatically in calculations. Otherwise, the simulation will run at an incorrect speed.
|
|
Modifies [member motion_velocity] if a slide collision occurred. To get the latest collision call [method get_last_slide_collision], for more detailed information about collisions that occurred, use [method get_slide_collision].
|
|
When the body touches a moving platform, the platform's velocity is automatically added to the body motion. If a collision occurs due to the platform's motion, it will always be first in the slide collisions.
|
|
Returns [code]true[/code] if the body collided, otherwise, returns [code]false[/code].

<member name="collision/safe_margin" type="float" setter="set_safe_margin" getter="get_safe_margin" default="0.001">
|
|
Extra margin used for collision recovery when calling [method move_and_slide].
|
|
If the body is at least this close to another body, it will consider them to be colliding and will be pushed away before performing the actual motion.
|
|
A higher value means it's more flexible for detecting collision, which helps with consistently detecting walls and floors.
|
|
A lower value forces the collision algorithm to use more exact detection, so it can be used in cases that specifically require precision, e.g at very low scale to avoid visible jittering, or for stability with a stack of character bodies.

<member name="floor_block_on_wall" type="bool" setter="set_floor_block_on_wall_enabled" getter="is_floor_block_on_wall_enabled" default="true">
|
|
If [code]true[/code], the body will be able to move on the floor only. This option avoids to be able to walk on walls, it will however allow to slide down along them.
|
|
</member>
|
|
<member name="floor_constant_speed" type="bool" setter="set_floor_constant_speed_enabled" getter="is_floor_constant_speed_enabled" default="false">
|
|
If [code]false[/code] (by default), the body will move faster on downward slopes and slower on upward slopes.
|
|
If [code]true[/code], the body will always move at the same speed on the ground no matter the slope. Note that you need to use [member floor_snap_length] to stick along a downward slope at constant speed.

</member>
|
|
<member name="floor_max_angle" type="float" setter="set_floor_max_angle" getter="get_floor_max_angle" default="0.785398">
|
|
Maximum angle (in radians) where a slope is still considered a floor (or a ceiling), rather than a wall, when calling [method move_and_slide]. The default value equals 45 degrees.
|
|
</member>
|
|
<member name="floor_snap_length" type="float" setter="set_floor_snap_length" getter="get_floor_snap_length" default="0.1">
|
|
Sets a snapping distance. When set to a value different from [code]0.0[/code], the body is kept attached to slopes when calling [method move_and_slide]. The snapping vector is determined by the given distance along the opposite direction of the [member up_direction].
|
|
As long as the snapping vector is in contact with the ground and the body moves against `up_direction`, the body will remain attached to the surface. Snapping is not applied if the body moves along `up_direction`, so it will be able to detach from the ground when jumping.

If [code]true[/code], the body will not slide on slopes when calling [method move_and_slide] when the body is standing still.
