Expressions

Player Expressions

Some commands have <player_expr> as an argument. While you can use a player index here, you can also target multiple players, or players with a specific name. Stock Halo commands do not support player expressions.

Expression	Effect
*	This is a wildcard expression which matches any number of any characters. Using it by itself will match all players.
me	This matches the player executing the command.
rt	This matches all players on the red team.
bt	This matches all players on the blue team.
pl	This matches all non-admins.
admin	This matches all admins.
rand	This matches a random player.
randred	This matches a random player on red team.
randblue	This matches a random player on blue team.

Decimal and Integer Expressions

In certain commands, some commands have <decimal_expr> and <int_expr>. While you can simply set the value to whatever positive value you want (negative values require the : expression), using an expression can be useful depending on what the goal is.

<int_expr> is an integer value. Some integers may have lower upper-bound limits due to the size of the integer.

<decimal_expr> is a float value and is a decimal, meaning 0.0 to 1.0. One percent is equal to 0.01.

Expression	Effect
:<number>	Set a value to an exact value. This is not required for positive values but is required for negative values.
+<number>	Add a value to the current value.
-<number>	Subtract a value from the current value. If you are intending to set a value to a negative value, use the : expression.
*<number>	Multiply the current value with a value.
/<number>	Divide the current value with a value.
%<number>	Set the remainder of the current value divided by the given value (modulo).
