/*
Leaves a trail of lit, shared-vision torches behind characters.
Intended to help players see where they've been on maps with dynamic lighting enabled.
Great for dungeon crawls and hex crawls.
*/
/* Major TODO List:
Working On:
- testing
Broken:
- colors aren't permanent.. if the list of active mappers changes, the aura colors change.
Need:
- set light_otherplayers for shared-vision mode and unique-vision mode
- change what's stored in gmnotes. right now it's the parent token_id, but it could be a JSON string with more options.
- test with a group of 3 or 4
- implement 1-click installation
- add more gui buttons: for when a token is selected already. Toggles seem to work well too.
- reorganize gui
- test inherited DROP_DISTANCE on maps with different grid settings. It's currently assuming 70 pixels per unit.
- write a test plan, for bugchecking
Nice To Have:
- add an option to limit the number of lightcrumbs and reuse the oldest ones
- offload math to Stephen L's VectorMath and PathMath libraries
- implement occlusion testing - can you see the last lightcrumb, or is it blocked by a dynamic lighting wall?
- see Stephen L's "It's a Trap" script
- consider making the torches burn out over time.
- see The Aaron's "Torch" script
Consider:
- Maybe players shouldn't have access to config options. Check for GM.
DONE:
- add option to change the radius of the displayed aura.
- add option to change the graphic: invisible token would be nice.
- update register case to drop a lightcrumb right away
- add dynamic configuration options for the radius and dimness of the light
- offset the lightcrumbs so they fall 1 unit behind the targetToken, along the vector of [lastMove, currentLocation]
- set the default offset to 0 and change behaviour such that lightcrumbs drop at lastlocation instead of current.
- something's wrong with dropping tokens. they're invisible until you change the icon. Fixed: lastmove.split was producing strings, not numbers
- make an option to use offsets instead of lastlocation (offsets look better, but might penetrate walls)
- consider an option so each light crumb is only controlled by the player that dropped it.
- add a deregister command, to remove a token from the list of activeMappers
- option to use token's original visual properties to set the lightCrumb's properties.
- Some tokens don't have owners, but we rely on that for controlleby and getAuraColor... come up with a workaround
- change aura color for each specific player.
- modify the reset function, so it only clears the current page and torches from the current token
- modify handleTokenMove, such that crumbs are dropped based on light settings rather than drop distance
- modify handleTokenMove or getLightCrumbsFromLayer such that only those owned by the token are considered for purposes of calculating shortest distances.
- remove one trail should work if you click on a torch instead of a character.
- set defaults to inherit lighting, unique vision mode with drop distance based on light_radius
- In Unique vision mode, findNearest Lightcrumb should check the parentToken
- In Inherited Light Settings mode, drop distance should depend on light radius // this doesn't work for very large radii, unless you also implment occlusion testing
- add a superClear function to remove the tokens from the GM Layer
- change Help to handout instead of chat.
- rewrite the help text -- see if you can make a popout handout
- when shared-vision is true, all the auras should be the same color
NOTES:
- we use the gmnotes field to store the tokenID of the parent mapper. If you modify the gmnotes, things might break
- we don't do rigorous error checking, so if you pass values to !LightCrumb through macros or the chat interface, things might break
