Stopping Power - Damage slows you down

This is a simple, lightweight addon that makes players temporarily slow down when they take damage, similar to the movement of the Left 4 Dead or Counter-Strike games. This should make combat more realistic and immersive and visceral and all sorts of other buzzwords!

This addon is made in an uninvasive way, so it should be compatible with virtually every other addon.

If you want an addon that sets each player's max speed based on how much health they have, check out Crippling Damage!


If you want to tinker with the numbers, it is easily configured using the in-game console:

stoppower_enable 1
Enables or disables the addon

stoppower_dmg_mult 0.05
Sets the base slowdown amount per damage taken. A value of 1.0 means the player is brought down to 0% speed after taking 1 damage.

The slowdown also receives a configurable multiplier based on what kind of damage was received. The defaults for each are listed below. A value of 2.0 for these means the slowdown is doubled; a value of 0.0 means the slowdown is negated.

stoppower_dmg_mult_armor 0.8 -- applied if the player has any armor
stoppower_dmg_mult_bullet 1.0 -- bullets
stoppower_dmg_mult_drown 0.0 -- drowning
stoppower_dmg_mult_energy 0.9 -- lasers, plasma, electricity, etc.
stoppower_dmg_mult_explosion 1.1 -- explosions
stoppower_dmg_mult_falling 0.25 -- falling
stoppower_dmg_mult_fire 0.9 -- fire
stoppower_dmg_mult_impact 1.1 -- props, vehicles, and blunt melee attacks
stoppower_dmg_mult_poison 0.1 -- poison (e.g. from poison headcrabs)
stoppower_dmg_mult_slash 1.0 -- slashes (includes almost all HL2 NPC melee attacks)
stoppower_dmg_mult_toxin 0.9 -- acid, radiation, etc

stoppower_minimum_speed_mult 0.1
Sets the slowest multiplier allowed. A value of 0.0 means the player can be slowed to 0% speed.

stoppower_recovery_speed 0.66
Sets the amount of speed recovered every second. A value of 1.0 means the player is brought up from 0% speed to 100% speed in 1 second.

stoppower_recovery_delay 0.5
Sets the number of seconds before recovery starts.

stoppower_autoreset_type 1
0: Never auto-reset
1: Auto-reset on death
2: Auto-reset on spawn
Different values may work better for different gamemodes or preferences. Regardless of what you set, players' speeds should return to normal after dying.

Use this command to reset all players' slowdowns. This may be helpful if you run into bugs.

stoppower_tick_time 0.05
Sets how frequently Stopping Power updates player speeds. Increase this value if the addon is too taxing on your server.
