how do i change an industry's requirements/production?

[MatthewH86]

Hello,

main point as in title. which file would i need to alter to change an industry's requirements/production?

or is it more complicated than changing a few values?

thanks in advance

I'm pretty sure you can't change requirements and production as long as you don't change source, but lets hope it will be possible when new gfx format is out (don't want "when" from me)

well i've downloaded the source files but i can't find anything about where the industry settings are. just about drawing the them.

i do actually want to change the source

One way to do it would be to implement Action 00 for industries/industry tiles.
The structure is shown here.Then The file you would need to work on would be in newgrf.c.

Then, you'll have to drill into build_industry.h and make writable arrays everything that is below _industry_spec.

That would be a nice project...

The structure is shown here.

That's only half of it, though. Action0IndustryTiles is also required to make a working industry.

MatthewH86, for just changing values in game you can use CTRL+C and the tick "Enable changing production values", however for better behaviour you can just use my Smooth_economy_patch (v 2.0) where you can configure the behaviour.

Why would you want to do this anyway??? Takes to the realism out of it.

It's like saying:

'I want to let a wood accept livestock, so erm... '

Well I suppose that you could do this if you wanted. You have a right. What did you have in mind?
