How to make marker on map with pawno script?
What marker? Default player have marker on the radar (and u can set it manual):
SetPlayerMarker(playerid,colour);
Also you can remove it:
RemovePlayerMarker(playerid);
If u want create map icon, u can't do this i think, cause this command don't included in a_vcmp.inc:
SetPlayerMapIcon(playerid,#,x,y,z,iconid,color);
