floatsin

warning

This function starts with a lowercase letter.

Description

Get the sine from a given angle. The input angle may be in radians, degrees or grades.

Name	Description
Float:value	The angle from which to get the sine.
anglemode:mode	The angle mode to use, depending on the value entered. (default: radian)

Returns

The sine of the value entered.

Examples

GetPosInFrontOfPlayer(playerid, Float:distance, &Float:x, &Float:y, &Float:z)
{
    if (GetPlayerPos(playerid, x, y, z)) // this functions returns 0 if the player is not connected
    {
        new Float:z_angle;
        GetPlayerFacingAngle(playerid, z_angle);

        x += distance * floatsin(-z_angle, degrees); // angles in GTA go counter-clockwise, so we need to reverse the retrieved angle
        y += distance * floatcos(-z_angle, degrees);

        return 1; // return 1 on success, the actual coordinates are returned by reference
    }
    return 0; // return 0 if the player isn't connected
}

Notes

warning

GTA/SA-MP use degrees for angles in most circumstances, for example GetPlayerFacingAngle. Therefore, it is most likely you'll want to use the 'degrees' angle mode, not radians. Also note that angles in GTA are counterclockwise; 270° is East and 90° is West. South is still 180° and North still 0°/360°.
