A3D_GetRouteTurnCount

Number of turns of a route.

native A3D_GetRouteTurnCount(Route:routeid);

Parameters

Parameter	Description
Route:routeid	Route to read.

Returns

• The number of turns.
• 0 when the route does not exist.

Remarks

Only the turns at junctions count, where a driver chooses a way. A road that bends between junctions makes no turn. A route of a few kilometres has about ten.

Example

stock PrintTurns(Route:routeid) {
    new
        Float:x,
        Float:y,
        Float:z,
        Float:distance,
        A3D_TURN:turn
    ;

    for (new index, count = A3D_GetRouteTurnCount(routeid); index != count; ++index) {
        turn = A3D_GetRouteTurn(routeid, index, x, y, z, distance);
        printf("after %.0f metres, turn %i", distance, _:turn);
    }
}
