The most common way the game uses limits is clamping a value to fall within a certain range. The helper function <code>GLimitLm</code> exists for this purpose; it takes a pointer to an <code>LM</code> and float value <code>g</code>, and returns the value of <code>g</code> clamped to fall between <code>gMin</code> and <code>gMax</code> inclusive.

There are some limits that are so commonly used they are defined as global values in the game’s code. One example is <code>g_lmZeroOne</code> which defines a limit by the interval [0,1].

LM (limit) is a data structure used in Sly Cooper and the Thievius Raccoonus. Limits are used to clamp values to ensure they fall within a certain range.

Usage

The helper function GLimitLm is used to clamp a float value to fall within a given limit.. It takes a pointer to an LM and float value g, and returns the value of g clamped to fall between gMin and gMax inclusive.

Some limits are so commonly used they are defined as global values in the game’s code. One example is g_lmZeroOne which defines a limit on the interval [0,1].
