Purupuru triggers

[GoogleCodeExporter]

Using a wheel and pedals in F355 Challenge, the throttle would die off when the 
pedal was near or at the maximum amplitude.

In PuruPuru.cpp I found this:

if(axis > 0)  return  axis/128

But I thought the reach of the trigger was 255 and the the axis 32767 which 
would make the return value 256 I guess. I found this formula produces better 
values if the maximum values are as I assumed:

if(axis > 0)  return  (axis * 2 + 1)/257

Well, 32767/128 gives 255.99 which I assume should be truncated to 255 since 
it's INT/INT.

I'll compile one with your method, so you can test it.

I changed every Axis to Trigger with your method.

This is the problem.... Axis: -32768 to 32767. The negative case... would give 
256. XD

KrossX3,

I got an issue that revolves around setting the trigger inputs to other inputs. 
In Test Drive Le Mans, midway thro a race, i changed the trigger inputs to my 
right analog stick input. RT > RY+, LT > RY- 

RT > RY+ works, however, LT > RY- doesn't. That means the brake doesn't work. 
Could you look at that? Thanks.

I'm using the xbox360 controller with purupuru input plugin.

It's probably the same thing. Give the link a try and test it.

Tried it.

I think i understand the issue now. If I move the stick all the way down (max), 
it will register nothing, anything less than max will register the brakes. The 
issue is still there with your new r46.

That is odd. It should've worked with torkel104's method. I'll change it and 
add some safety checks.

Try this one: http://www.mediafire.com/?zujmmmme2mj

Is the way it was before, but with the safety checks.

Sorry, my bad. I left the plugin in the main folder.

It worked!! Thanks!

I used the safety checks of the second file. Basically, because it was already 
done so I only had to review it. =P
