C++ (Cpp) GetMoveAngle Examples

Example #1

File: Player.cpp Project: MartinUbl/kiv-ups-agarserver

void Player::Update(uint32_t diff)
{
    m_session->Update(diff);

    if (!IsUpdateEnabled())
        return;

    if (IsMoving() && !IsDead())
    {
        float dx = cos(GetMoveAngle())*diff*m_playerSpeed;
        float dy = sin(GetMoveAngle())*diff*m_playerSpeed;

        Position plpos(m_position.x + dx, m_position.y + dy);
        Relocate(plpos, true);
    }
}
