I have a question about air pollution. I'd like to make it so that the larger parks reduce this somewhat, while raising garbage pollution. In the GreenPark3 bit (the largest green park), I notice that there is a "pollution at center" line, with different values for air, water, garbage and radiation. The last two are 0x00000000, which I can easily change to 0x00000001 for garbage (to raise garbage pollution, right?). But the air pollution value is 0xFFFFFFF1, which has a decimal value of 4294967281! I'm stumped. So the question is, how do I adjust this to lower air pollution? And if I wanted a negative number, how can I get this in hexadecimal? The second question is radius of effect. I guess the pollution radii (6,3,0,0) could be amended to (12,3,3,0) to make the effect for air and garbage more noticeable? And the final question regards the decline in effect as one gets farther away from the park. I could find no line which suggested something of the sort. Please help. Pretty please. And thanks. PS. The flip side to this is that I can't find any information for air pollution values under say, "Industrial Dirty".
