Example

Interprets an expression an writes the result to the string associated with the stringID given.

Expression syntax

A block is a part of an expression in the form of (sigil character)(opening brace)(variable name)(closing brace), such as ?{count}.

Three type of blocks can appear in expressions:

String variable block: Syntax: ${stringID_variable} Replaced with the string associated with stringID

Variable value block: Syntax: ?{number_variable} Replaced with the value of the variable ( in decimal form ).

Variable sequence block: Syntax: @{first_variable} Replaced with the string produced by interpreting the variables as characters, starting from first_variable, until a zero value is found. See StrLoad and StrSave

Usage example

short playername
short itemname

begin ScriptEffectStart

set itemname to StrGetName
set playername to player.StrGetName
StrExpr itemname "${playername}'s ${itemname}"
StrSetName itemname

StrDel playername
StrDel itemnamename

end
