movedOverPoints() Function

• Introduced in version 1.3.b75

Use to check if a token has moved through a shape that is defined by an array of pixel coordinates (formatted like the one received from getLastPath() or the onTokenMove event.

Returns a JSON array with coordinates of all cells that are

• all or partially in the defined shape and
• were traversed by the token.

Where each point is dependent on the grid type:

• Square: Coordinates are the top-left corner.
• Hex: Coordinates are the center point of the cell.
• Isometric: Coordinates are the right-most point of the cell.
• Gridless: Returns just the top-left corner of the token's ending location.

Usage

movedOverPoints(points)
movedOverPoints(points,path)

Parameters

• points - JSON array of X/Y coordinate X/Y pairs that defines a polygon
• path - JSON array of X/Y coordinate such as that returned by getLastPath()

Example

<!-- lets define a shape -->

[h: jsonArray = json.append("",
    json.set("", "x",   0, "y",   0),
    json.set("", "x",   0, "y", 100),
    json.set("", "x", 100, "y", 100),
    json.set("", "x",   100, "y", 0)
)]

<!-- check if token in context has moved through that shape -->
[r: movedOverPoints(jsonArray)]

With Second Parameter

[h: jsonArray = json.append("",
    json.set("", "x", 250, "y", 250),
    json.set("", "x", 250, "y", 550),
    json.set("", "x", 550, "y", 550),
    json.set("", "x", 550, "y", 250)
)]

Last Path: [r: lastPath = getLastPath()]

Moved Over: [r: movedOverPoints(jsonArray,lastPath)]
