Torque 3D's Player class has three main modes of movement over land: sprinting, running, and crouching. Some are designed to allow a player to sprint as much as they want, but perhaps with other limitations while sprinting. This is the default method of sprinting in the Torque 3D templates. Other game designs allow the player to sprint only for short bursts before the player becomes "tired". In this recipe, we will learn how to set up the Player class such that sprinting uses up a pool of energy that slowly recharges over time; and when that energy is depleted, the player is no longer able to sprint.

How to do it...

2. Find the sprinting section of the Datablock instance and make the...
