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

[Values]
Randoms = 0 ~ 1999

And in code:

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

This will give you a random number, eg:

 Value: 1675

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

[Values]
Angles = 0 ~ 45 ~ 360

orxU32 value = orxConfig_GetU32("Angles");

 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)

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

1. orxMath_GetSteppedRandomFloat
2. orxMath_GetSteppedRandomU32
3. orxMath_GetSteppedRandomS32
4. orxMath_GetSteppedRandomU64
5. orxMath_GetSteppedRandomS64

An example:

orxFLOAT val = orxMath_GetSteppedRandomFloat(1, 100, 2.1);
orxLOG ("Value: %f", val);

 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

A little tricker, but the same nonetheless:

[Values]
MyRandomVector = (1, 3, 5) ~ (0, 0.1) ~ (2, 4, 6)

• 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)

You can get more detail and examples in the Creation Template here or in your local repo of Orx.
