Math counter

Template:Base point It stores and manipulates a numerical value. It can trigger on reaching user-defined maximum or minimum values, or output its value every time it changes. It also has the ability to perform simple mathematical functions. When the math_counter is disabled, it will become read-only until re-enabled.

In code, it is represented by theCMathCounterclass, defined in thelogicentities.cppfile.

Keyvalues

Initial Value (startvalue) ([todo internal name (i)]) <float>

Starting value for the counter.

Minimum Legal Value (min) ([todo internal name (i)]) <float>

Minimum legal value for the counter. If min=0 and max=0, no clamping is performed.

Maximum Legal Value (max) ([todo internal name (i)]) <float>

Maximum legal value for the counter. If min=0 and max=0, no clamping is performed.

Name (targetname) <string>[ Edit ]

The name that other entities refer to this entity by, via Inputs/Outputs or other keyvalues (e.g. parentname or target).
Also displayed in Hammer's 2D views and Entity Report.

Start Disabled (StartDisabled) <boolean>

Stay dormant until activated (with theEnableinput).

Inputs

Add <floatRedirectInput/float>

Add an amount to the counter and fire the OutValue output with the result.

Divide <floatRedirectInput/float>

Divide the counter by an amount and fire the OutValue output with the result.

Note:If this causes a division by zero, the counter will ignore the input.

Multiply <floatRedirectInput/float>

Multiply the counter by an amount and fire the OutValue output with the result.

SetValue <floatRedirectInput/float>

Set the counter to a new value and fire the OutValue output with the result.

SetValueNoFire <floatRedirectInput/float>

Set the counter to a new value without firing any outputs.

Subtract <floatRedirectInput/float>

Subtract an amount from the counter and fire the OutValue output with the result.

SetHitMax <floatRedirectInput/float>

Set the upper bound of the counter and fire the OutValue output with the current value.

SetHitMin <floatRedirectInput/float>

Set the lower bound of the counter and fire the OutValue output with the current value.

GetValue

Causes the counter to fire its OnGetValue output with the current value of the counter. Used for polling the counter when you don't want constant updates from the OutValue output.

SetMaxValueNoFire <floatRedirectInput/float> (in all games since )

Set the counter to the MaxValue without firing any outputs.

SetMinValueNoFire <floatRedirectInput/float> (in all games since )

Set the counter to the MinValue without firing any outputs.

EnableDisable:

Enable / Disable

Enable/disable this entity from performing its task. It might also disappear from view.

Outputs

OutValue <floatRedirectInput/float>

Fired when the counter value changes.

Note:Generates the value of the math_counter into the parameters section of an Output Statement. To use a generated parameter, just leave the field reading <none>.

Tip:Useful in tandem with logic_case and logic_compare

OnHitMin

Fired when the counter value meets or goes below the min value. The counter must go back above the min value before the output will fire again.

OnHitMax

Fired when the counter value meets or exceeds the max value. The counter must go below the max value before the output will fire again.

OnGetValue <floatRedirectInput/float>

Fired in response to the GetValue input. Used for polling the counter when you don't want constant updates from the OutValue output.

Note:Generates the value of the math_counter into the parameters section of an Output Statement. To use a generated parameter, just leave the field reading <none>.

Tip:Useful in tandem with logic_case, math_remap and logic_compare.

OnChangedFromMin  (in all games since )

Fired when the counter value changes from the minimum value.

OnChangedFromMax  (in all games since )

Fired when the counter value changes from the max value.
