Entity contains several components and related system logics. Component is pure data, like velocity, status and so on. System is about pure logic, it is a bunch of status-less functions.</p> <p>For high performance project, component&rsquo;s pure data and system&rsquo;s pure logic feature is important, which helps reduce CPU cache missing and provide cleaner code structure.</p> <p>However, in some cases, I choose to mix some component (data) and some system (logic) into one single macro component. For example, I&rsquo;ve got one macro component called <code>MovementComponent</code>, which contains <code>moveSpeed</code>, <code>jumpSpeed</code>, <code>movementStatus</code> data, as well as <code>ExecuteMove()</code>, <code>ExecuteJump()</code> logic.</p>
