Damage, in ROBLOXian terms, is a reduction of the value of a ROBLOXian's humanoid's health, usually effected by weapons or bricks with scripts. The default health setting for a ROBLOXian humanoid is 100, and as such, when a humanoid takes 100 damage, the associated player makes a childish "Oof!" sound and falls apart, and a countdown will be started until the player respawns.
Types of Damage
Environmental damage is damage that cannot be configured in any way by a place creator. The only type of environmental damage that currently exists in ROBLOX is worldborder damage, which causes a ROBLOXian to die if they go too far outside the ROBLOXian world. The most common example of this is when a ROBLOXian falls off a brick into the bottom of the ROBLOXian world. After a few seconds, the ROBLOXian will die.
Local damage is damage that can be caused by elements which can be modified by a place creator. Currently, only scripts can create damage. Local damage can be effected on humanoids by scripts by either applying the takeDamage() method, or by manually setting a humanoid's health to a level lower than it was before. For example, say there was a character named Telamon within the workspace. To damage him by 50 points, we could either do this:
workspace.Telamon.Humanoid.Health = workspace.Telamon.Humanoid.Health - 50Either of these two modus can be used in order to damage a humanoid. Such modus are commonly used in scripts to create a brick that damages people, or a weapon that, when used, damages others. Here are some examples of damage conductors:
