actor mcontroller

The mcontroller table sometimes contains functions relating to the actor movement controller.

This section of mcontroller documentation refers to the ActorMovementController lua bindings. There is other documentation referring to the mcontroller table for base MovementControllers.

float mcontroller.mass()

Returns the configured mass of the movement controller.


Vec2F mcontroller.position()

bool mcontroller.isColliding()

Returns whether the movement controller is currently colliding with world geometry or a PhysicsMovingCollision.


bool mcontroller.isNullColliding()

Returns whether the movement controller is currently colliding with null world geometry. Null collision occurs in unloaded sectors.

float mcontroller.liquidPercentage()

Returns the percentage of the collision poly currently submerged in liquid;


LiquidId mcontroller.liquidId()

Returns the liquid ID of the liquid that the movement controller is currently submerged in. If this is several liquids this returns the most plentiful one.


bool mcontroller.onGround()

Returns whether the movement controller is currently on ground.


bool mcontroller.zeroG()

Returns true if the movement controller is at a world position without gravity or if gravity has been disabled.


bool mcontroller.atWorldLimit([bool bottomOnly])

Returns true if the movement controller is touching the bottom or the top (unless bottomOnly is specified) of the world.


void mcontroller.setAnchorState(EntityId anchorableEntity, size_t anchorPosition)

Anchors the movement controller to an anchorable entity at the given anchor index.


void mcontroller.resetAnchorState()

Reset the anchor state.


EntityId, int mcontroller.anchorState()

Returns ID of anchored entity and index of the anchor position.


void mcontroller.setPosition(Vec2F position)

Sets the position of the movement controller.


void mcontroller.setXPosition(float x)

Sets the horizontal position of the movement controller.


void mcontroller.setYPosition(float y)

Sets the vertical position of the movement controller.


void mcontroller.translate(Vec2F direction)

Moves the movement controller by the vector provided.


void mcontroller.setVelocity(Vec2F velocity)

Sets the velocity of the movement controller.


void mcontroller.setXVelocity(Vec2F xVelocity)

Sets the horizontal velocity of the movement controller.


void mcontroller.setYVelocity(Vec2F yVelocity)

Sets the vertical velocity of the movement controller.


void mcontroller.addMomentum(Vec2F momentum)

Adds (momentum / mass) velocity to the movement controller.


void mcontroller.setRotation(float angle)

Sets the rotation of the movement controller. Angle is in radians.


ActorMovementParameters mcontroller.baseParameters()

Returns the base movement parameters.


bool mcontroller.walking()

Returns whether the actor movement controller is currently walking.


bool mcontroller.running()

Returns whether the actor movement controller is currently running.


int mcontroller.movingDirection()

Returns the direction that the actor movement controller is currently moving in. -1 for left, 1 for right.


int mcontroller.facingDirection()

Returns the facing direction. -1 for left, 1 for right.


bool mcontroller.crouching()

Returns whether the controller is currently crouching.


bool mcontroller.flying()

Returns whether the controller is currently flying.


bool mcontroller.falling()

Returns whether the controller is currently falling.


bool mcontroller.canJump()

Returns whether the controller can currently jump.


bool mcontroller.jumping()

Returns whether the controller is currently jumping.


bool mcontroller.groundMovement()

Returns whether the controller is currently in a ground movement state. Movement controllers can be in ground movement even when onGround returns false.


bool mcontroller.liquidMovement()

Returns whether the controller is currently in liquid movement mode.


controls

The actor movement controller has a set of controls. Controls can be set anywhere and are accumulated and evaluated after all scripts are run. Controls will either override previously set controls, or combine them.

Controls are either cleared before every script update, or can be set to be manually cleared.


void mcontroller.controlRotation(float rotation)

Rotates the controller. Each control adds to the previous one.


void mcontroller.controlAcceleration(Vec2F acceleration)

Controls acceleration. Each control adds to the previous one.


void mcontroller.controlForce()

Controls force. Each control adds to the previous one.


void mcontroller.controlApproachVelocity(Vec2F targetVelocity, float maxControlForce)

Approaches the targetVelocity using the force provided. If the current velocity is higher than the provided targetVelocity, the targetVelocity will still be approached, effectively slowing down the entity.

Each control overrides the previous one.


void mcontroller.controlApproachVelocityAlongAngle(float angle, float targetVelocity, float maxControlForce, bool positiveOnly = false)

Approaches the targetVelocity but only along the provided angle, not affecting velocity in the perpendicular axis. If positiveOnly, then it will not slow down the movementController if it is already moving faster than targetVelocity.

Each control overrides the previous one.


void mcontroller.controlApproachXVelocity(float targetVelocity, float maxControlForce)

Approaches an X velocity. Same as using approachVelocityAlongAngle with angle 0.

Each control overrides the previous one.


void mcontroller.controlApproachYVelocity(float targetVelocity, float maxControlForce)

Approaches a Y velocity. Same as using approachVelocityAlongAngle with angle (Pi / 2).

Each control overrides the previous one.


void mcontroller.controlParameters(ActorMovementParameters parameters)

Changes movement parameters. Parameters are merged into the base parameters.

Each control is merged into the previous one.


void mcontroller.controlModifiers(ActorMovementModifiers modifiers)

Changes movement modifiers. Modifiers are merged into the base modifiers.

Each control is merged into the previous one.


void mcontroller.controlMove(float direction, bool run)

Controls movement in a direction.

Each control replaces the previous one.


void mcontroller.controlFace(float direction)

Controls the facing direction.

Each control replaces the previous one.


void mcontroller.controlDown()

Controls dropping through platforms.


void mcontroller.controlCrouch()

Controls crouching.


void mcontroller.controlJump()

Controls starting a jump. Only has an effect if canJump is true.


void mcontroller.controlHoldJump()

Keeps holding jump. Will not trigger a new jump, and can be held in the air.


void mcontroller.controlFly(Vec2F direction)

Controls flying in the specified direction (or {0, 0} to stop) with the configured flightSpeed parameter.

Each control overrides the previous one.


bool mcontroller.autoClearControls()

Returns whether the controller is currently set to auto clear controls before each script update.


void mcontroller.setAutoClearControls(bool enabled)

Set whether to automatically clear controls before each script update.


void mcontroller.clearControls()

Manually clear all controls.
