Not all scripts are local offcourse...
When the game starts it reads some scripts global,like init.sqs,intro.sqs.From within this global place U can exec more serverscripts([] exex "globalscript.sqs") or more local scripts:
?!(local server):[] exec "localscript.sqs"Call the hint in global scripts and everybody will see it,call it from a local place and only U will see it.
You can further split up the audiance of the hintbox with the command player or combinations in global scripts like:
?side player == WEST:hint"only WEST can read this"
?!alive player:hint "Rest in Peace dummy
"
?player==flagowner flag east:hint"keep running dont look back
"
?vehicle player ==player:hint"dont leave the keys behind ffs"
Or U can use a Radio trigger with the hint in the On Activation.
