-Then if you wanted to use the song length actor on the options screen, you can\r
-access it like this:\r
+(NB: RegisterGlobal must be called on CurrentStepsP[1/2]Changed since that message is broadcast AFTER\r
+the bpm display has been updated, therefore when we call RegisterGlobal it gets the correct value)\r
\r
-local SongLength = GetGlobal("TotalTime")\r
+Then we can set up callbacks to pull out the low and high BPMs like so:\r
+\r
+local function LowBPM( BPMDisplay )\r
+ local pos = string.find(BPMDisplay, "-")\r
+ if pos ~= nil then return string.sub(BPMDisplay,1,pos-1) else return BPMDisplay end\r
+end\r
+\r
+local function HighBPM( BPMDisplay )\r
+ local pos = string.find(BPMDisplay, "-")\r
+ if pos ~= nil then return string.sub(BPMDisplay,pos+1) else return BPMDisplay end\r
+end\r
+\r
+RegisterGlobalCallback("HighBPM", HighBPM)\r
+RegisterGlobalCallback("LowBPM", LowBPM)\r
+\r
+Then if you wanted to use the BPM on a different screen you could do it like this:\r
+\r
