A_LinedefExecuteFromArg

This Action may only work in UDMF maps. For objects that are to be used in Binary use A_LinedefExecute instead.

A_LinedefExecuteFromArg is an action that executes a linedef executor. The calling sector is the one the actor is in when the action is performed. The tag of the executor's trigger linedef is determined by the argument input box, determined by Var1.

Note that negative numbers can also be used for Arguments; tag numbers 32768 to 65536 displayed in map editors are in actual fact tag numbers -32768 to -1, though this action allows use of either version for ease and compatibility.^{[confirm? – discuss]}
