Copy and Paste Series

First off I would like to thank EvilClone for his Cloaking tutorial for which served as a base for this.
By adjusting the renderamounts of the player we can make him invisible. The next section should be fairly easy just to copy and paste, but please give me some credit.

1. Open mp workspace-> goto New.
2. C/C++ source file name it, stealthsuit.cpp.
3. Copy and Paste!

Stealthsuit.cpp


/*
* This is the invisible pack
* they must have this equipped in order to be cloaked
* Thought that would be best to prevent invisible frags
* As they move with this equipped they are visible
* But when they stop they are entirely invisible!
*/

Remember to define the weapon in weapons.h and weapons.cpp. See the NVGoggles tutorial for how to do it.

Download the sprite file.

Make the stealthsuit take battery power.
Old in BLUE.
New in RED.

Lets add a new line in Cloak()

//Put the cloaking stuff here
if (m_pPlayer->pev->armorvalue <= 3)
{
ClientPrint(m_pPlayer->pev, HUD_PRINTCENTER, "You cannot cloak due\n to battery power\n");
return;
}
else
{
m_pPlayer->pev->armorvalue -= 2; //takes more battery power to turn on than off
}
m_pPlayer->pev->renderamt = cloak;

Then in UnCloak()

//Uncloaking here
m_pPlayer->pev->armorvalue -= 1;
m_pPlayer->pev->renderamt = cloak;

Finally in WeaponIdle()

if (m_pPlayer->pev->armorvalue <= 2)
{

ClientPrint(m_pPlayer->pev, HUD_PRINTCENTER, "You battery power too\n low to remain cloaked!");

Uncloak()
}
