I'd rather using Streamer checkpoint in this problem

Make sure you have this include:

pawn Код:

#include <streamer>

then create this:

pawn Код:

new CP;//making variable

then, use function callback onplayerenterdynamiccp:

pawn Код:

public OnPlayerEnterDynamicCP(playerid,checkpointid)
{
if(checkpointid == CP)
{
ShowPlayerDialog(..........)//Your code here!
}
return 1;
}

Wish this helped
