A3D_ApplyImpulse

Push a moving physics object through its centre of mass.

native bool:A3D_ApplyImpulse(Physic:physicid, Float:x, Float:y, Float:z);

Parameters

Parameter	Description
Physic:physicid	Physics object to push.
Float:x	Impulse on the X axis, in kilograms times metres per second.
Float:y	Impulse on the Y axis.
Float:z	Impulse on the Z axis.

Returns

• true when the impulse was applied.
• false when physicid is not a moving physics object.

Remarks

An impulse changes the velocity by the impulse divided by the mass, so the same push throws a light ball far and barely moves a heavy crate. An impulse of 10.0 gives a ball of half a kilogram 20 metres per second and a crate of 20 kilograms half a metre per second.

The push goes through the centre of mass, so it adds no spin. It wakes the object.

Example

A punch that pushes whatever object it hits.

stock Punch(playerid, Physic:physicid) {
    new
        Float:angle
    ;

    GetPlayerFacingAngle(playerid, angle);
    A3D_ApplyImpulse(physicid, -floatsin(angle, degrees) * 40.0, floatcos(angle, degrees) * 40.0, 10.0);
}
