<hr><a name="_details"></a><h2>Detailed Description</h2>
<h3>template<typename T><br>
class Ogre::Controller< T ></h3>
Instances of this class 'control' the value of another object in the system.
<p>
<dl compact><dt><b>
Remarks: </b><dd>
<a class="el" href="classOgre_1_1Controller.html">Controller</a> classes are used to manage the values of object automatically based on the value of some input. For example, a <a class="el" href="classOgre_1_1Controller.html">Controller</a> could animate a texture by controlling the current frame of the texture based on time, or a different <a class="el" href="classOgre_1_1Controller.html">Controller</a> could change the colour of a material used for a spaceship shield mesh based on the remaining shield power level of the ship.
<p>
The <a class="el" href="classOgre_1_1Controller.html">Controller</a> is an intentionally abstract concept - it can generate values based on input and a function, which can either be one of the standard ones supplied, or a function can be 'plugged in' for custom behaviour - see the <a class="el" href="classOgre_1_1ControllerFunction.html">ControllerFunction</a> class for details. Both the input and output values are via <a class="el" href="classOgre_1_1ControllerValue.html">ControllerValue</a> objects, meaning that any value can be both input and output of the controller.
<p>
Whilst this is very flexible, it can be a little bit confusing so to make it simpler the most often used controller setups are available by calling methods on the <a class="el" href="classOgre_1_1ControllerManager.html">ControllerManager</a> object. </dl><dl compact><dt><b>
