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 in the token's path that overlap with the area defined by the given points.

Where each coordinate pair returned 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)]
