This object represents a token instance placed in a token container. Token instances are based on token prototypes that define
the bitmap used for the token. A token container can contain several instances of one prototype.
By default, token instances can be manipulated by the host and all clients. The token container may be locked, in which case vectors may be
drawn out from the token by the clients to indicate movement requests. Tokens can also be toggled non-modifiable which disallows client interaction
altogether.
Tokens flagged targetable can be clicked by players to indicate they are targeting the corresponding token. Several clients can target one token.
Token instances do not have direct scripting function definitions, but use a handler based notification scheme. Care should be taken to unregister
handlers whenever the objects containing the handler script are destroyed.
Interface
addUnderlay
function addUnderlay(
size, color, [mode]
)
Add an underlay to the token. Underlays are colored areas drawn based on the grid squares below the token.
The size of underlays is given in squares and is measured as a radius from the token centre to the grid square
centres. Thus, an equal value as the underlay size will result in a different sized overlay area based on
whether the token is situated at a grid square centre or a grid line intersection.
Only scripts running on the session host can set this property.
Parameters
size (number)
The size of the underlay in grid squares
color (string)
The color of the underlay, in the form '#aarrggbb' where 'aa' represents the transparency
(alpha) of the desired color. If alpha is zero or not defined, FF is assumed.
mode (string) [optional]
If this string contains the substring "gmonly", this overlay will be displayed on the host only.
If the string contains the substring "hover", the overlay will only be drawn when the mouse cursor is hovering
over the token. The flags can be combined.
delete
function delete(
)
Destroy the token instance, removing it from the token container.
getContainerNode
function getContainerNode(
)

Return values
(databasenode)
The
databasenode representing the image containing the token

onActivation
handler
function onActivation(

)
This handler is called when the target token is activated.
Parameters
target (tokeninstance)
onClickDown
handler
function onClickDown(
target, button
)
This function is called when a mouse button is pressed down on the token. If this function is not defined or returns false, the onClickRelease function is not called.
Warning
The token interface for click events is different than other objects in that a handler must be registered to intercept click events.
Parameters

This function should return true if it handled the event and the processing of the event should be stopped. A value of false indicates that the default
framework functionality for the this particular control should not be executed, but the processing should continue for the element below this control, if any. A return value of
nil (or the absence of a return statement) indicates that the framework should continue handling the event normally.
onClickRelease

Return values
(boolean)
This function should return true if it handled the event and the processing of the event should be stopped. A value of false indicates that the default
framework functionality for the this particular control should not be executed, but the processing should continue for the element below this control, if any. A return value of
nil (or the absence of a return statement) indicates that the framework should continue handling the event normally.

(boolean)
This function should return true if it handled the event and the processing of the event should be stopped. A value of false indicates that the default
framework functionality for the this particular control should not be executed, but the processing should continue for the element below this control, if any. A return value of
nil (or the absence of a return statement) indicates that the framework should continue handling the event normally.
registerMenuItem
function registerMenuItem(
label, icon,
...
)
This function registers a new user defined menu item. If the user selects the item, the script is notified
of this through the onMenuSelection handler, if registered.
The menu item is defined by specifying the bitmap and label to use, as well as the position of the item on the menu. The position is
given as a number value. To define entries in submenus, use multiple number values, with the first being the position value of the outermost
submenu, and the last being the position of the actual menu item in the innermost submenu.
Trying to redefine an existing menu item will fail.
