Ok, recently I make a lot of TPT LUA scripts. I even tried with not LUA (Like C++, Compiling) but I failed. Nevermind.

Last time I wrote METH (methane) script. Nothing special, just adds gas that has similar properties to GAS, but it's olive green. And I added some transitions, only with fire. I wonder is there a way to make transition where pressurized PLNT makes METH. Like "access" Basic TPT elements, change some of their properties. If I can do that easily (By script or so), tell me please. If not - guess what, ill just leave it in this form.

Here is script:

-- Functionally identical to restrict_flt() in source
function restrict(f, min, max)
    if f < min then
        return min
    elseif f > max then
        return max
    end
    return f
end

If you are good in TPT LUA system and have some free time, feel free to help me. Thanks.

thanks.

Edit: didn't work when i did that:

print("Methane by IlikeUssr ")
print("Changelog: ")
print("Version 1.0 - Release ")
print("Version 1.1(In dev.) - Now you can make METH from pressurized PLNT!")
print("-------------------------------------------------------------------")
print("Enjoy! ")
-- Functionally identical to restrict_flt() in source
function restrict(f, min, max)
if f < min then
return min
elseif f > max then
return max
end
return f
end

Can i fix it somehow?

Also, i changed from 4 pres. to 2.
