Crippling Damage

This is a simple, lightweight addon that changes players' max speeds when they reach configurable health thresholds, similar to the movement of the Left 4 Dead games. This should make combat more realistic and immersive and visceral and all sorts of other buzzwords!

Although I didn't even look at the code from it, I have to mention Sninctbur's "Damage Slow" addon, which clearly inspired this addon's functionality. However, Crippling Damage is more flexible for customization and should be more compatible (e.g. it won't interfere with any other addons that change player speeds, works regardless of the player's normal max speed, etc). In addition to making players slower at certain thresholds, you can also use this addon to make players speed up when they hit a given health threshold.

By default, the addon sets 66% max speed at 40% health and 33% max speed at 15% health. These numbers are inspired by Left 4 Dead, so they should feel pretty familiar. If you prefer to use raw health instead of percentages (e.g. 66% max speed at 40 hp instead of at 40% hp), or if you want to add, remove, or change thresholds, see "Customizing" below.

If you're looking for an addon that will temporarily slow players down whenever they take damage, check out Stopping Power!


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

crippledmg_enable 1
Enables/disables the addon

crippledmg_as_percentage 1
When 1, thresholds are set as a % of the player's max HP; otherwise just the raw HP value

This command prints the current thresholds to the console (server-side)

crippledmg_thresholds_set 40 0.66
crippledmg_thresholds_set 15 0.33
Sets or creates a threshold at the given hp with the given speed multiplier

Removes the threshold at the given hp

crippledmg_file crippledmg_thresholds.txt
Sets the name of the config file to use for save/load (located in garrysmod/data/). The file is automatically generated and saved to when making changes to thresholds.

Forces a reload from the file specified by crippledmg_file. An initial load happens automatically when Lua starts. Use this command after crippledmg_file if you are switching files.

Reset all players' current speeds. This may be helpful if you encounter bugs.

crippledmg_tick_time 0.05
Sets how frequently Crippling Damage will check player HP. Increase this value if the addon is too taxing on your server.
