trackable

comment

Trackables can register both click and hover events by players. But they don't provide a way to get the triggering player. In fact the only (as of writing) functions that have the trackable type in their signature are:

• CreateTrackable
• TriggerRegisterTrackableHitEvent
• TriggerRegisterTrackableTrackEvent
• GetTriggeringTrackable
• SaveTrackableHandle
• LoadTrackableHandle

To create a trackable which can distinguish the triggering player we simply create a trackable for each player but with a locally different path:

function CreateTrackableForPlayer takes player p, string path, real x, real y, real facing returns trackable
    if GetLocalPlayer() != p then
        set path = ""
    endif
    return CreateTrackable(path, x, y, facing)
endfunction

Now using something like hashtables or lua tables we can attach the correct player to the trackable handle and retrieve it by accessing GetTriggeringTrackable. You can use the same technique to attach other information like the trackables position, facing, etc.

note

See CreateTrackable for a way to create a trackable with a non-zero z-coordinate.
