Legacy:PlayInfo

UT2003 :: Object >> PlayInfo (Package: Engine)

Collects information about Info classes for the web admin interface.

GameInfo, GameReplicationInfo, AccessControl and all loaded Mutator classes get the opportunity to add their user-editable properties to the PlayInfo object. The web admin interface displays all those properties and allows users to modify them interactively.

Class	Function
GameInfo	FillPlayInfo (static)
GameReplicationInfo	FillPlayInfo (static)
AccessControl	FillPlayInfo (static)
Mutator	MutatorFillPlayInfo

The implementation of MutatorFillPlayInfo in Mutator was a little buggy in earlier versions of UT2003, so the mutator configuration options aren't registered reliably for the web admin interface. In version 2186 and later this has been fixed and you can implement it like in one of the following examples

Either directly overwrite MutatorFillPlayInfo...

function MutatorFillPlayInfo(PlayInfo PlayInfo)
{
    // add current class to stack
    PlayInfo.AddClass(Class);
 
    // now register any mutator settings
    PlayInfo.AddSetting("Mutators", "bMyFirstSetting",  "First mutator setting",  0, 0, "Check");
    PlayInfo.AddSetting("Mutators", "bMySecondSetting", "Second mutator setting", 0, 0, "Check");
 
    // remove mutator class from class stack
    PlayInfo.PopClass();
 
    // call default implementation
    if (NextMutator != None)
        NextMutator.MutatorFillPlayInfo(PlayInfo);
}

...or FillPlayInfo.

static function FillPlayInfo(PlayInfo PlayInfo)
{
    // call superclass implementation, which adds the mutator class to the stack
    Super.FillPlayInfo(PlayInfo);
 
    // now register any mutator settings
    PlayInfo.AddSetting("Mutators", "bMyFirstSetting",  "First mutator setting",  0, 0, "Check");
    PlayInfo.AddSetting("Mutators", "bMySecondSetting", "Second mutator setting", 0, 0, "Check");
 
    // remove mutator class from class stack
    PlayInfo.PopClass();
}

PlayInfoData

struct PlayInfoData
{
	var const Property    ThisProp;	   // Pointer to property
	var const class<Info> ClassFrom;   // Which class was this Property from
	var const string      SettingName; // Name of the class member
	var const string      DisplayName; // Display Name of the control (from .INT/.INI File ?)
	var const string      RenderType;  // Type of rendered control
	var const string      Grouping;    // Grouping for this parameter
	var const string      Data;        // Extra Data (like Gore Level Texts)
	var const string      ExtraPriv;   // Extra Privileges Required to set this parameter
	var const byte        SecLevel;    // Sec Level Required to set this param. (Read from Ini file afterwards)
	var const byte        Weight;      // Importance of the setting compared to others in its group
	var const bool        bGlobal;     // GlobalConfig Property ? (Set by native function)
	var const string      Value;	   // Value of the setting
};

Methods

All PlayInfo methods are native and final with the exception of Init() which is only final.

Clear() 

Clears the Settings array.

AddClass(class<Info> Class) 

Prepares the PlayInfo object for subsequent AddSetting calls relating to the given class.

PopClass() 

Removes the last class added to the class stack with the AddClass method, thus returning to the previously added class.

AddSetting(string Group, string PropertyName, string Description, byte SecLevel, byte Weight, string RenderType, optional string Extras, optional string ExtraPrivs) 

Validates the given data and adds an entry to the Settings array. The given PropertyName must correspond to an existing config variable in the current class. (Existing entries can be changed with the StoreSetting function.)

bool SaveSettings() 

Saves stored settings to an .ini file.

bool StoreSetting(int index, coerce string NewVal, optional string RangeData) 

Validates the given data and sets an element of the Settings array.

int FindIndex(string SettingName) 

Returns an index into the Settings array corresponding to the given property name.

SplitStringToArray(out array<string> AStr, string Str, string Divider) 

Splits the given string into an array of elements that were separated by the given divider substring (for instance, a comma).

Init() 

Prints a list of all currently stored settings to the log.

RenderType

This is an explaination of the render types. Render types tell WebAdmin which HTML widget to display for the variable.

Check 

Checkbox. This is associated with variable with a boolean type. Whether it's checked, or not, is based on the value of the variable.

Text 

Input field used for strings and numeric data. This render type can use the optional Extras parameter in AddSetting to determine the length of the field, and for the valid value range.

"Length;Min Value:Max Value" // for numerics
"Length" // for alphanumerics

For example, "3;0:200" would create an input field of length 3 and only accept values between 0 and 200. Values outside the range will default to closest minimum or maximum value.

For alphanumeric fields you can specify a maximum length or leave this out completely, which will most likely make the imput field too small.

Select 

Drop down select box: This render type requires the optional Extras parameter in AddSetting for the selection list. The parameter is structured as follows:

"Value1;Text1;Value2;Text2; ... ValueN;TextN"

For example, if I had three items with unique ids the parameter might look like this.

"0;Unreal Rifle Sound;1;UT Rifle Sound;2;Lightning Gun Sound"

The value of the variable will determine which item is selected as the default.
