Rooftops plus dynamic lighting

rooftops.js

// a script to remove rooftops if a player enters a building
// move the player flag to the page you want to use this on
// draw your dynamic lighting lines on your building
// use a roof token, best if it's rotation is an integer multiple of 90 degrees (0, 90, 180, 270)
// name the roof token "roof", without the quotes. Preferable put it on map layer
// drag in player tokens. That is, tokens either assigned to players, or representing characters assigned to player
// type !RoofReady into chat, or better yet, use it from a macro. Alternatively, dragging the player flag to the page does this.
// should be good to go. Let me know if there are errors please :)
// other feature: !RoofDLOff and !RoofDLOn will now turn off or on the dynamic lighting interaction of the script. Default is 'on'.
// if you want default to be off, change the declaration on line 21 to read: var dlInteraction = false;
// finally, the default is to turn off the roof when characters are under it. You can change this by editing the 
// interactionRange variable on line 22. 0 Is when they're under the roof, 1 is within 5 feet, 2 10 ft, etc.
// Alternatively, you can type !RooftopRange x, where x is the number of 5 foot squares away from which it will interact.
