Overview

BiterBias allows you to tune the biter-spitter spawn ratio, and optionally make up for the difficulty difference by increasing the base spawn rate and the chance of larger biters once they can appear.

BiterBias is designed to reduce frustration in the early game, where gun turrets are the only defences available, and where spitters can - by virtue of having a larger range - attack and destroy them with impunity. This mod will allow you to convert any fraction of spitter spawns to biter spawns - much as spitter spawners already do if the evolution level is low enough that spitters are either disallowed outright or biased against.

Since spitters are harder to defend against than biters, the mod offers optional compensatory difficulty by allowing you to increase the base spawn rate of either every enemy or biters individually. It also enables you to increase the chance assigned to larger biters once their evolution thresholds are reached. That is, the larger biters will never appear earlier than they otherwise would, but will be more common once they do. This is particularly noticeable with blue biters, whose spawn chance is very low at their first allowable evo level.

Configuration Settings

This mod contains several config options to modify values and behaviors - such as for balance or server safety concerns, or simply personal taste - to your preferences. Note that several settings may have bounds imposed on their values, either logically or explicitly; these can usually be seen in the actual settings files or ingame. These are listed in order found in the source code, which is generally the order in which they were added; They may be present in a different order ingame or in the configuration files.
The settings for the mod, when installed, can be found ingame, in the mod settings menu.

Global spawn rate multiplier

Type: double
Current Default Value:
1.0
Change this to affect the global spawn rate; it is multiplied by all spawn rates (and by biterRate for biter spawn rate). 1.0 is vanilla and default.

Biter spawn rate multiplier

Type: double
Current Default Value:
1.0
Change this to modify the biter spawner spawn rate. 1.0 is vanilla settings.

Biter bias factor

Type: double
Current Default Value:
0.33
Change this to modify the bias factor, that is, the Biter/Spitter spawn ratio. 1.0 is vanilla settings; at 0.5, 50% of spitter spawns become biter spawns. At 0.25, 75% do.

Increased probability of larger biters

Type: bool
Current Default Value:
true
To compensate for the reduced difficulty (since spitters are more dangerous than biters), increase biter spawn size (as per the evolution factor). Note that this does not make any size appear earlier, just more likely once it does appear.
