Onoffable shields and sfxtypes?

[code_man]

I noticed that onoffable works on weapons, but it doesnt seem to work for shields and sfxtypes.
Now for simbase there is such a building and it uses those, but its problematic that its on constantly and i wish to change this.
Should i write a gadget to do this or is there a way to do this with unitdef tags?

PS: Sorry for the barrage of topics today, but i think its better to have a 100 threads for a one problem each than the other way round, hope thats ok.

BA shields (corgate and armgate) can be toggled on and off. Take a look at those and report back if it does not yield results.
