EVENT_MANAGER:RegisterForUpdate

Doh, I didn't even think about checking it myself like this:

Lua Code:

EVENT_MANAGER:RegisterForUpdate("RegisterTest", 3000, function() d("RegisterTest 1") end)
EVENT_MANAGER:RegisterForUpdate("RegisterTest", 3000, function() d("RegisterTest 2") end)

Only outputs: RegisterTest 1
So I guess you can't reregister it to update it. You have to unregister it & then reregister it.

Which also lead me to figuring out it returns true, false if it gets registered or not:

Lua Code:

local bRegistered1 = EVENT_MANAGER:RegisterForUpdate("RegisterTest", 3000, function() d("RegisterTest 1") end)
d(tostring(bRegistered1))   -- prints true
 
local bRegistered2 = EVENT_MANAGER:RegisterForUpdate("RegisterTest", 3000, function() d("RegisterTest 2") end)
d(tostring(bRegistered2))   -- prints false

Although other problems also can cause a return of false:

Lua Code:

-- the function is nil
local bRegistered3 = EVENT_MANAGER:RegisterForUpdate("RegisterTest", 3000)
d(tostring(bRegistered3))   -- prints false

So I guess you can't rely on a return of false to know that something is already registered.
I'm still trying to figure out a way to determine if something is already registered or not.
