A3D_IsValidObject

Whether a physics object, a static object or a zone exists.

native bool:A3D_IsValidObject(Physic:physicid);

Parameters

Parameter	Description
Physic:physicid	Physics object to check.

Returns

• true when it exists.
• false when it does not.

Remarks

Ids are reused, so a valid id may belong to a newer object than the one a script kept long ago. Keep ids in variables that are reset on destroy, or mark objects with A3D_SetExtra.

Example

stock bool:IsBallInPlay(Physic:ball) {
    if (!A3D_IsValidObject(ball)) {
        return false;
    }

    return A3D_IsMoving(ball);
}
