it would be cool if you could add vtk support to all cars, tanks and locomotives..
or you could change line 81+ to ...
local function has_vtk_category(entity)
if not entity.grid then return false end
for id,name in pairs(entity.grid.prototype.equipment_categories) do
if name == "vtk-armor-plating" then
return true
end
end
return false
end

local function set_entity_to_armor(entity)
entity_to_armor = nil
if entity ~= nil and has_vtk_category(entity) then
debug("entity to armor set to "..entity.name)
entity_to_armor = entity
end
end

...to allow modders to add support for your mod on their own

Hello,

Thanks for the feedback, I'll take look at this it would be most helpful indeed !

I've added support in 0.5.0 thanks again for the input, not much missing for it to work !
