Move To

The Move To behavior moves an object to a position at a maximum speed with acceleration and deceleration. It also supports rotating the object so it turns towards its target, and can add multiple waypoints to move to in sequence.

Move To properties

Max speed
The maximum speed the object will move at, in pixels per second.
Acceleration
The rate at which the object will accelerate to the maximum speed, in pixels per second per second. Use 0 to disable acceleration, meaning the object will immediately start moving at the maximum speed.
Deceleration
The rate at which the object will decelerate towards its target, in pixels per second per second. Use 0 to disable deceleration, meaning the object will come to an abrupt stop without slowing down. The object will only slow down towards its last position; if there are further waypoints to move to, it will continue accelerating up to the maximum speed. Note that the deceleration also imposes a stopping distance during which the object must be slowing down, which in some cases may prevent the object reaching its maximum speed.
Rotate speed
The rate the object will turn towards its target position, in degrees per second. Use 0 to disable turning, meaning the object will always move directly towards the target. Note a slow rotate speed results in a large turning circle, which can have awkward results if the object has to navigate through several close waypoints. For this reason it's recommended to use a high rotate speed.
Set angle
When enabled, the object angle will be set to the angle it is moving at. If disabled the movement will not affect the object angle.
Stop on solids
If enabled, movement will stop if the object collides with something with the Solid behavior, and trigger On hit solid. If disabled solids are ignored.
Enabled
Whether the behavior is initially enabled or disabled. If disabled, it can be enabled at runtime using the Set enabled action.

Move To conditions

Compare speed
Compare the object's current speed in pixels per second.
Is enabled
True if the behavior is currently enabled.
Is moving
True if the object has a target position it is moving towards.
On arrived
Triggered whenever the target position is reached. This is triggered for every waypoint if there are multiple waypoints to move to.
On hit solid
Triggered if Stop on solids is enabled and the object collided with a solid.

Move To actions

Move to position
Move to object
Start moving towards a position, given either by layout co-ordinates or an object (or optionally an image point on the object). If Mode is Direct, any existing waypoints are removed, so the object will immediately move towards the given position. If Mode is Add waypoint, it will instead add a new waypoint to move to after all existing waypoints have been reached.
Move along Pathfinding path
This is an alternative to the Pathfinding behavior's Move along path action. It only works with a Pathfinding behavior on the same object, and like the Pathfinding action can only be used after On path found triggers. The 'Move To' behavior uses a different algorithm for moving along waypoints, and this action lets you use its approach instead of the built-in Pathfinding movement.
Move along timeline
Move along timeline (by name)
Add all the points from the X and Y property tracks in a timeline track. The timing is ignored; the positions are treated only as a sequence of waypoints to move along. This is useful for using a timeline to visually design a path to follow in the Layout View. See the Move along path example for a demonstration.
Set angle of motion
Set the angle the object is currently moving at, in degrees.
Stop
Stop any current movement. This also removes all waypoints.
Set speed
Set the current movement speed in pixels per second. Note this cannot exceed the maximum speed, nor can it exceed the current speed while within the stopping distance, since increasing the speed while decelerating would cause the object to miss its target.
Set acceleration
Set deceleration
Set enabled
Set max speed
Set rotate speed
Set stop on solids
Set the corresponding properties. For more information see Move to properties above.

Move To expressions

MovingAngle
The current angle in degrees the object is moving at.
Speed
The current speed the object is moving at, in pixels per second.
TargetX
TargetY
The current position in layout co-ordinates that the object is moving towards. When multiple waypoints are used, this is the current waypoint.
WaypointCount
WaypointXAt(index)
WaypointYAt(index)
Use these expressions to access the full list of waypoints added, given in layout co-ordinates.
