So can some one help me with how to make the parameter.
Ill try to explain it very simple, so some things may not be the correct way to name it, but hopefully it makes it clear to you what to do
There are 3 things you need to do:
1. Add some textstrings to your .lng file (that shows up, so you can make a decision)
2. Add the code for the parameter (at the beginning of your code)
3. Add where the parameter is active (in the item-part of the roadtype)
1.
Add this to your .lng file:
Code: Select all
#Roadtype StockRoute Parameter
STR_PARAM_NAME_DISABLE_ROADTYPE_STOCKROUTE :Disable Roadtype StockRoute
STR_PARAM_DESC_DISABLE_ROADTYPE_STOCKROUTE :Use this option to use disable roadtype StockRoute
In this case I used name STOCKROUTE, up to you to rename that to something else if you add more parameters (or want to use a parameter in another GRF)
This will show up like this if you go to the parameter settings of your GRF (in this example I use two parameters, for roadtype Seawaterway and Canal, rather than StockRoute:

The first textstring shows up at the decision, the second one is additional text that you can see at the bottom.
2.
In your code you need to add something at the very beginning of your code, looks like this:
- Example799.png (7.53 KiB) Viewed 1668 times
There you need to add something like this:
Code: Select all
param 0 {
param_disable_roadtype_stockroute{
type: bool;
name: string(STR_PARAM_NAME_DISABLE_ROADTYPE_STOCKROUTE);
desc: string(STR_PARAM_DESC_DISABLE_ROADTYPE_STOCKROUTE);
}
}
If you want to add more parameters, you need to change param 0 to param 1, 2,... maximum is param 63 (so 64 in total, including 0)
And offcourse change STOCKROUTE to something else
IT IS EXTREMELY IMPORTANT TO PLACE THIS PART OF THE PARAMETER-CODE
BEFORE THE } AT THE END OF THE Define-GRF-block!!!
It has to be part of the Define-GRF-block
3.
Now we get to the action
Scroll down to the Define-item-block of your roadtype, looks something like this:
- Example800.png (28.14 KiB) Viewed 1668 times
3a.
Place this line of code at the beginning of the Define-item-block:
3b.
Place this line of code at the end of the Define-item-block:
Thats all
If you want to add more parameters in a single GRF, then
Becomes
to maximum
What you now have done is that Roadtype StockRoute is standard active, and you can use a Parameter to disable it.
Hope this works for you, let me know if you need more help/explanation.
