and a power supply:
int m_iMaxPower = 100;
float flRechargeRate = recharge_rate;

{

{
m_flDrainRemainder -= flChargeAmount;
return;
}
else
{
flChargeAmount -= m_flDrainRemainder;
m_flDrainRemainder = 0.0f;
}
}
m_flChargeRemainder += flChargeAmount;
int nPowerToAdd = (int)m_flChargeRemainder;
m_flChargeRemainder -= nPowerToAdd;
//---------------------------------------------------------------
//---------------------------------------------------------------
if ( FlashlightIsOn() )
{
m_iPower -= nPowerToAdd;
if ( m_iPower == 0 )
{
m_flChargeRemainder = 0.0f;
}
if ( m_iPower <= 5 )
{
FlashlightTurnOff();
}
}
else
{
if ((m_iPower < m_iMaxPower) )
{
m_iPower += nPowerToAdd;
if ( m_iPower == m_iMaxPower )
{
m_flChargeRemainder = 0.0f;
}
}
}
but im having some problems linking the power supply to the hud element. What
exactly should i do about it?
Thanks in advance,
Adrian
