pawn Code:
// A single 3D label:
native DestroyDynamic3DTextLabel(Text3D:id);
// You should store the ID for the 3D label in a variable so you can check whether it's valid, delete/update it or get the text later on
PHP Code:
native Text3D:CreateDynamic3DTextLabel(const text[], color, Float:x, Float:y, Float:z, Float:drawdistance, attachedplayer = INVALID_PLAYER_ID, attachedvehicle = INVALID_VEHICLE_ID, testlos = 0, worldid = -1, interiorid = -1, playerid = -1, Float:streamdistance = 100.0);
native DestroyDynamic3DTextLabel(Text3D:id);
native IsValidDynamic3DTextLabel(Text3D:id);
native GetDynamic3DTextLabelText(Text3D:id, text[], maxlength = sizeof text);
native UpdateDynamic3DTextLabelText(Text3D:id, color, const text[]);
native DestroyAllDynamic3DTextLabels();
native CountDynamic3DTextLabels();
