I am now doing some small NewGRF, and have run into problem. I can't seem to be able to make an user parameter switch work. At this moment it does not even compile. Compiler says, that there is an unrecognized identifier at line 143. At that line is an if switch, which I want to use to disable some stuff, if boolean parameter is set at "1". Exactly at that line is some literal train id from my code, which I want to disable if user decides to do so. Here is the code:
Code: Select all
grf {
grfid: "MG\04\01";
name: string(STR_GRF_NAME);
desc: string(STR_GRF_DESCRIPTION);
version: 0;
min_compatible_version: 0;
param 1{
metro {
type: bool;
name: string(STR_PARAM1_NAME);
desc: string(STR_PARAM1_DESC);
def_value: 0;
bit: 0;
names: {
0: string(STR_PARAM1_ON);
1: string(STR_PARAM1_OFF);
};
}
}
}
