Collision results

actor_colliding_down ( self ) : stingray.Actor Returns the actor, if any, that the mover is standing upon.

Parameters

self :

stingray.Mover

Specifies the object instance that this function will act on. You must always provide this self parameter when you call this function. You must use the dot . calling syntax, not the object-oriented colon : calling syntax.For more information, see Object lifetimes and userdata binding, or this page in the Lua documentation.

Returns

stingray.Actor

The actor that was last collided with in the downward direction.

collides_down ( self ) : boolean Indicates whether or not the Mover is colliding in the downward direction: i.e. whether the surface it is hitting is a walkable surface.

Parameters

self :

stingray.Mover

Specifies the object instance that this function will act on. You must always provide this self parameter when you call this function. You must use the dot . calling syntax, not the object-oriented colon : calling syntax.For more information, see Object lifetimes and userdata binding, or this page in the Lua documentation.

Returns

boolean

Parameters

self :

stingray.Mover

Specifies the object instance that this function will act on. You must always provide this self parameter when you call this function.

Returns

integer

The number of frames the mover has been flying.

This function returns 1 for the first frame the mover is flying.

standing_frames ( self ) : integer Returns the number of frames the mover has been "standing" on a surface.

Parameters

self :

stingray.Mover

Specifies the object instance that this function will act on. You must always provide this self parameter when you call this function. You must use the dot . calling syntax, not the object-oriented colon : calling syntax.For more information, see Object lifetimes and userdata binding, or this page in the Lua documentation.

Returns

integer

The number of frames the mover has been standing.

The mover is considered to be "standing" if it is colliding downward with a walkable surface: a surface whose slope is less than the maximum slope value set for the Mover.

This function returns 1 for the first frame the mover is standing.

Controlling Mover behavior

max_slope_angle ( self ) : number Returns the maximum slope angle that the mover can walk on.

Parameters

self :

Returns

number

The maximum slope angle set for the mover, in radians.

set_collision_filter ( self, filter ) Changes the collision filter used by the mover.

Parameters

self :	stingray.Mover	Specifies the object instance that this function will act on. You must always provide this self parameter when you call this function. You must use the dot . calling syntax, not the object-oriented colon : calling syntax.For more information, see Object lifetimes and userdata binding, or this page in the Lua documentation.
filter :	string	The new collision filter to set for the mover.

Returns

This function does not return any values.

set_max_slope_angle ( self, slope ) Sets the maximum slope angle that the mover can walk on.

Parameters

self :	stingray.Mover	Specifies the object instance that this function will act on. You must always provide this self parameter when you call this function. You must use the dot . calling syntax, not the object-oriented colon : calling syntax.For more information, see Object lifetimes and userdata binding, or this page in the Lua documentation.
slope :	number	The new maximum slope angle to set for the mover, in radians.

Returns

This function does not return any values.

Positioning

fits_at ( self, position, allow_move ) : boolean, stingray.Vector3? Indicates whether or not the mover fits at the specified position without colliding with any world geometry.

Parameters

self :	stingray.Mover	Specifies the object instance that this function will act on. You must always provide this self parameter when you call this function. You must use the dot . calling syntax, not the object-oriented colon : calling syntax.For more information, see Object lifetimes and userdata binding, or this page in the Lua documentation.
position :	stingray.Vector3	The position to place the mover.
allow_move :	number?	If non-zero, specifies the distance to search for a non-colliding position. The ? notation indicates that this type is optional: there may be zero or one instances of it.

Returns

boolean	Returns true if the mover fits at the position, or false otherwise.
stingray.Vector3?	If a non-colliding position was found, it is returned as the second paramter. The ? notation indicates that this type is optional: there may be zero or one instances of it.

move ( self, offset, delta_time ) Attempts to move the mover by the specified position.

Parameters

self :	stingray.Mover	Specifies the object instance that this function will act on. You must always provide this self parameter when you call this function. You must use the dot . calling syntax, not the object-oriented colon : calling syntax.For more information, see Object lifetimes and userdata binding, or this page in the Lua documentation.
offset :	stingray.Vector3	The vector along which the mover slides.
delta_time :	number	The delta time in seconds. Used to resolve interactions with kinematic platforms.

Returns

This function does not return any values.

The mover will slide against physical objects.
