====== Getting Stepped Random Values from Config ======

You would be familiar with retrieving a random value from the config by writing:

<code ini>
[Values]
Randoms = 0 ~ 1999
</code>

And in code:

<code c>
if (orxConfig_PushSection("Values")){
	orxU32 value = orxConfig_GetU32("Randoms");
	orxLOG ("Value: %d", value);
	
	orxConfig_PopSection();
}
</code>

This will give you a random number, eg:

   Value: 1675


===== Stepped Integers =====

You can also define **stepped** random values using the following format:

<code ini>
[Values]
Angles = 0 ~ 45 ~ 360
</code>

<code c>
orxU32 value = orxConfig_GetU32("Angles");
</code>

   Value: 270

In the example above, ''0 ~ 45 ~ 360'' would mean to define a range of values between 0 and 360, 45 steps apart.

Other examples would be:

   0 ~ 1 ~ 10  (standard number range of 1 to 10, steps of 1)
   0 ~ 1 ~ 1   (like a binary switch 0 or 1, same as 0 ~ 1)
   1 ~ 5 ~ 100 (1 to 100 in steps of 5)
   0 ~ 2 ~ 10  (an even number between 0 to 10)


===== Code examples =====

You can also do this from code using any of the following functions:

  - ''orxMath_GetSteppedRandomFloat''
  - ''orxMath_GetSteppedRandomU32''
  - ''orxMath_GetSteppedRandomS32''
  - ''orxMath_GetSteppedRandomU64''
  - ''orxMath_GetSteppedRandomS64''

An example:

<code c>
orxFLOAT val = orxMath_GetSteppedRandomFloat(1, 100, 2.1);
orxLOG ("Value: %f", val);
</code>

   11.50000

So the above would be floats 1 to 100 in steps of 2.1. You can get more details about those functions here: http://orx-project.org/orx/doc/html/group__orx_math.html


===== Stepped Vectors =====

A little tricker, but the same nonetheless:

<code ini>
[Values]
MyRandomVector = (1, 3, 5) ~ (0, 0.1) ~ (2, 4, 6)
</code>

  * X will be unconstrained between 1 and 2 (step = 0)
  * Y will be between 3 and 4 with a step of 0.1 and;
  * Z will be unconstrained between 5 and 6 (no Z component, which means: Z = 0)
