CollisionHandlerGravity

from acron.core import CollisionHandlerGravity

class CollisionHandlerGravity

Bases:

Bases: CollisionHandlerPhysical

A specialized kind of CollisionHandler that sets the Z height of the collider to a fixed linear offset from the highest detected collision point each frame. It’s intended to implement walking around on a floor of varying height by casting a ray down from the avatar’s head.

__init__()

add_velocity()

Adds the sepcified amount to the current velocity. This is mostly here allow this common operation to be faster for scripting, but it’s also more concise even in cpp.

property airborne_height → float

Return the height of the object from the ground.

The object might not necessarily be at rest. Use is_on_ground() if you want to know whether the object is on the ground and at rest.

property contact_normal → LVector3

get_airborne_height()

Return the height of the object from the ground.

The object might not necessarily be at rest. Use is_on_ground() if you want to know whether the object is on the ground and at rest.

static get_class_type()

get_contact_normal()

get_gravity()

Gets the linear gravity force (always plumb).

get_impact_velocity()

How hard did the object hit the ground. This value is set on impact with the ground. You may want to watch (poll) on is_on_ground() and when that is true, call get_impact_velocity(). Normally I avoid polling, but we are calling is_on_ground() frequently anyway.

get_legacy_mode()

returns true if legacy mode is enabled

get_max_velocity()

Retrieves the maximum speed at which the object will be allowed to descend towards a floor below it, in units per second. See set_max_velocity().

get_offset()

Returns the linear offset to add to (or subtract from) the highest detected collision point to determine the actual height at which to set the collider.

get_reach()

Returns the reach to add to (or subtract from) the highest collision point

get_velocity()

Gets the current vertical velocity.

Generally, negative values mean the object is in free fall; while postive values mean the object has vertical thrust.

A zero value does not necessarily mean the object on the ground, it may also be weightless and/or at the apex of its jump.

See Also: is_on_ground() and get_gravity()

property gravity → float

Gets/Sets the linear gravity force (always plumb).

property impact_velocity → float

How hard did the object hit the ground. This value is set on impact with the ground. You may want to watch (poll) on is_on_ground() and when that is true, call get_impact_velocity(). Normally I avoid polling, but we are calling is_on_ground() frequently anyway.

is_on_ground()

Is the object at rest?

property max_velocity → float

Getter

Retrieves the maximum speed at which the object will be allowed to descend towards a floor below it, in units per second. See set_max_velocity().

Setter

Sets the maximum speed at which the object will be allowed to descend towards a floor below it, in units per second. Set this to zero to allow it to instantly teleport any distance.

property offset → float

Returns/Sets the linear offset to add to (or subtract from) the highest detected collision point to determine the actual height at which to set the collider.

property on_ground → bool

Is the object at rest?

property reach → float

Returns/Sets the reach to add to (or subtract from) the highest collision point

set_gravity()

Sets the linear gravity force (always plumb).

set_legacy_mode()

Enables old behavior required by Toontown (Sellbot Factory lava room is good test case, lava and conveyor belt specifically). Behavior is to throw enter/exit events only for floor that the toon is in contact with

set_max_velocity()

Sets the maximum speed at which the object will be allowed to descend towards a floor below it, in units per second. Set this to zero to allow it to instantly teleport any distance.

set_offset()

Sets the linear offset to add to (or subtract from) the highest detected collision point to determine the actual height at which to set the collider.

set_reach()

Sets the reach to add to (or subtract from) the highest collision point

set_velocity()

Sets the current vertical velocity.

property velocity → float

Getter

Gets the current vertical velocity.

Generally, negative values mean the object is in free fall; while postive values mean the object has vertical thrust.

A zero value does not necessarily mean the object on the ground, it may also be weightless and/or at the apex of its jump.

See Also: is_on_ground() and get_gravity()

Setter

Sets the current vertical velocity.
