Custom Controls
User inputs are handled by the InputHandler,
which is part of SceneryBase
and Hubable
. Adding inputs can be done in an overwrite of the inputSetup
method of SceneryBase
. First a Behavior
needs to be added before a key can be assigned.
Adding a Behavior
A behavior defines an action which is executed when the corresponding keys are pressed. There are currently the following base behaviors from which can be inherited: ClickBehavior
, DragBehavior
, ScrollBehavior
.
In most cases a ClickBehavior
is used. Example:
In cases where the x
and y
screen positions of the cursor are not needed, they are just ignored. Adding a behavior to the InputHandler
is straightforward:
inputHandler
should be available from an overwrite of the inputSetup
method.
Assigning Keys to Behaviors
Assigning keys to a behavior works in a similar fashion:
This code assigned the earlier added behavior to the first mouse button.
Does the same but for the "M" key.
