This is a mod for the HBS BattleTech game that introduces a sliding modifier based upon the difference in tonnage between attacker and target. This is designed to combat the late-game bias towards heavies and assaults, at which point lights and medium units fall out of favor. This mod introduces a new 'size delta' attack modifier that penalizes heavier units shooting at lighter ones, and rewards lighter units shooting at larger ones.

This mod requires [https://github.com/iceraptor/IRBTModUtils/]. Grab the latest release of IRBTModUtils and extract it in your Mods/ directory alongside of this mod.

The attack modifier is calculated with the following formula:

• tonnageDelta = attackerTonnage - targetTonnage
• tonnageFraction = tonnageDelta / TonnageDivisor (from mod.json)
• rawModifier = tonnageFraction * TonnageMulti (from mod.json)
• If rawModifier > 0, then the highest integer value is taken (i.e. -13.7 becomes -13)
• If rawModifier < 0, then the lowest integer value is taken (i.e. 14.9 becomes 14)

That's it.

Only mechs and vehicles have tonnage in the HBS game; turrets and buildings do not. These units are treated as having 'virtual' tonnage.

Turrets are given the value specified in mod.json for VirtualTonnage.LightTurret, VirtualTonnage.MediumTurret, VirtualTonnage.HeavyTurret if they have the unit_light, unit_medium,. or unit_heavy tag respectively. Turrets without one of these tags are given VirtualTonnage.DefaultTurret,

Buildings are given VirtualTonnage.Building regardless of their tags.

You can modify statistics - most commonly those from Custom Bundle - based on mech's tonnage, using StatisticsToAddPerTon.

The formula used is 1 + unitTonnage * addition. For example, if mod.json contained "CACIncomingHeatMult" : -0.0025, a 100 ton mech would take 75% heat damage (1 + 100 * -0.0025 = 0.75), while a 20-tonner takes 95% (1 + 20 * -0.0025 = 0.95). This is useful for any other statistic you want to scale by weight

This applies only to mechs, not vehicles, buildings or turrets!

There are a handful of settings in the mod.json, by which you can configure the mod as you please.
