[Modding] new enhancements for units

[Dudekahedron]

Hi Faf,
Me again. Relatively simple question;
I am trying to create an enhancement for a shield generator:
Basically just adding a weapon who's muzzle is located on the shield?

From script.lua:

Code: Select all

    CreateEnhancement = function(self, enh)
       TShieldStructureUnit.CreateEnhancement(self,enh)
       local bp = self:GetBlueprint().Enhancements[enh]
       if not bp then return end
       # Restraining order
       if enh == 'RestrainingOrder' then
          local blueprint = self:GetBlueprint()
          CreateSlider(self,'muzzle', blueprint.Defense.Shield.ShieldSize, 0, 0, 1000, true)
          self:SetWeaponEnabledByLabel('PhasonBeam',true)
       elseif enh == 'RestrainingOrderRemove' then
          local blueprint = self:GetBlueprint()
          CreateSlider(self,'muzzle', -blueprint.Defense.Shield.ShieldSize, 0, 0, 1000, true)
          self:SetWeaponEnabledByLabel('PhasonBeam',false)
       end
    end,   

From unit.bp:

Code: Select all

    Enhancements = {
        RestrainingOrder = {
            BuildCostEnergy = 10000,
            BuildCostMass = 1000,
            BuildTime = 1000,
            Icon = 'cd',
            Name = 'Restraining Order',
            Slot = 'Back',
        },
        RestrainingOrderRemove = {
            BuildCostEnergy = 1,
            BuildCostMass = 1,
            BuildTime = 0.1,
            Icon = 'cd',
            Name = 'Remove Restraining Order',
            Prerequisite = 'RestrainingOrder',
            RemoveEnhancements = {
                'RestrainingOrder',
                'RestrainingOrderRemove',
            },
            Slot = 'Back',
        },
    },

The enhancement option doesn't appear for the unit, and I get weird glitchiness with the ACU (not sure if related), any ideas?

Code: Select all

I can think of a couple of things that might impact you here;

You'll need to define the Slots on your unit blueprint, refer to either the ACU or SCU for that. If the slots aren't defined, then the interface will throw errors, and that's likely what you're seeing. The key hint was the function 'CreateTabs'.

Secondly, you may need to define a weapon in your blueprint, like any other, and see that it's set to a disabled state when the unit is first created. I assume that you've done that by your use of the 'SetWeaponEnabledByLabel', but I just thought I'd mention it.

Thanks for the fast reply!
It was the slot definitions I didn't have, totally missed that! Weirdly, it doesn't seem to relate to the issues with the ACU though.
I had the weapon stuff already
thanks for the help!

Give an extensive look at Asdrubalvect Experimental Wars.The units have lots of modifications and improvements.The model must to contain all the new"hidden" features that you will put there,as bones and pieces that will appear after.
