Important:This entity stores values as strings, so if you specify one of the case as "1.50", then when you try to compare float it will not match, because the float will be "1.5", and not "1.50".
Tip:Use with logic_timer for extremely random events.

logic_case is a logical entity available in all 
Source games. It compares an input to up to 16 configured values, firing a corresponding output if there is a match (on InValue), or fires a random output (on PickRandom). Use logic_random_outputs for a weighted random output.
Important:This entity stores values as strings, so if you specify one of the case as "1.50", then when you try to compare float it will not match, because the float will be "1.5", and not "1.50".Tip:Use with logic_timer for extremely random events.Keyvalues
- Name (targetname) <string>[ Edit ]
- The name that other entities refer to this entity by, via Inputs/Outputs or other keyvalues (e.g.
parentnameortarget).
Also displayed in Hammer's 2D views and Entity Report.See also: Generic Keyvalues, Inputs and Outputs available to all entities
- Case 01 (Case01) to Case 16 (Case16) <string>
- The values to test against.
Inputs
- InValue <variant>
- Compares the Input value converted to string to the case values, and fires the appropriate output, if any.
- PickRandom <void>
- Fires a random OnCase output with at least one connection.
- PickRandomShuffle <void>
- Fires a random OnCase output with at least one connection, with no repeats until all cases have been picked, at which point the shuffle starts over.
Outputs
- OnCase01 to OnCase16 <void>
- !activator = activator of the input causing this
!caller = this entity
Fired when the input value equals the corresponding Case value.
- OnDefault <variant>
- !activator = activator of InValue input
!caller = this entity
Fired when the input value does not equal any of the Case values.
- OnUsed <variant> (only in
) - !activator = activator of InValue input
!caller = this entity
Fired when an input value is received, regardless of whether it matches a case. Outputs the same parameter type as was inputted with InValue input (i.e. if it was float this output will be of type float, the same applies to OnDefault output in)
