#define MATERIAL_ARMOR_COEFFICENT 0.05
|
|
/*
|
|
SEE code/modules/materials/materials.dm FOR DETAILS ON INHERITED DATUM.
|
|
This class of armor takes armor and appearance data from a material "datum".
|
|
They are also fragile based on material data and many can break/smash apart when hit.
|
|
|
|
Materials has a var called protectiveness which plays a major factor in how good it is for armor.
|
|
With the coefficent being 0.05, this is how strong different levels of protectiveness are (for melee)
|
|
For bullets and lasers, material hardness and reflectivity also play a major role, respectively.
|
|
|
|
|
|
Protectiveness | Armor %
|
|
0 = 0%
|
|
5 = 20%
|
|
10 = 33%
|
|
15 = 42%
|
|
20 = 50%
|
|
25 = 55%

30 = 60%

50 = 71%
