Perk Functions Explained
This script adds custom abilities to four base BO2 Zombies perks.
Here is what each perk function does:
- Speed Cola – Power-Up Magnet + Hidden Perks
When the player has Speed Cola (specialty_fastreload), the script grants two extra hidden perks:
- Fast Weapon Switch(
specialty_fastweaponswitch)
- Fast Grenade Toss (
specialty_fasttoss)
Additionally, the player can pull power-ups toward themselves by pressing the melee button.
How it works:
- Every time the player presses melee, the script checks for nearby power-ups.
- Any power-up within 1500 units moves toward the player over 0.3 seconds.
- There's a 1-second cooldown between pulls.
- PhD Flopper – Automatic Grenade Regeneration
When the player has PhD Flopper (specialty_flakjacket), they receive:
- A guaranteed frag grenade loadout
- Automatic regeneration of grenades over time
How it works:
- The script keeps track of the lethal grenade type the player has.
- Every 30 seconds, if the player has less than 4 grenades, they gain +1 grenade.
- Works with both frag and semtex (sticky).
- Quick Revive – Double Jump / Multi-Jump
When the player has Quick Revive (specialty_quickrevive), they gain the ability to double jump.
How it works:
-
The script listens for the jump button press.
-
The player has 2 extra jumps stored.
-
Each jump adds upward velocity:
self SetVelocity(self GetVelocity() + (0,0,300));
-
The jump charges reset automatically every 1.8 seconds.
This creates smooth, BO3-style multi-jump movement.
- Double Tap – Cashback (Bonus Points System)
After the player has had Double Tap active for a few seconds, they enable the Cash Back effect.
How it works:
- The script monitors the player’s score in real time.
- Whenever the player earns points, they get 50% extra points on top.
- Example: earning 100 points gives +50 bonus points.
- Only works while the player has Double Tap (
specialty_rof).
