Logic Flow:

To be able to gaff logic it is essential to know how game logic works. Custom features follow exactly math flow: Lucky O'Reilly - 03. Flow/Storyboards

This page will explain and provide examples on gaffing / emulation. Emulation parameters are exactly the same as gaff, the only difference it that they are provided as stream of data instead of xml tags

Animations can't be emulated. They might be only gaffed.

Gaffing / Emulating features

PAYTABLECOMPONENTSWAP

The only feature done through paytable feature section (which means is gaffed in old way) is gaffing reel swap through PAYTABLECOMPONENTSWAP feature.

PAYTABLECOMPONENTSWAP with id=0 is base game fature, id=1 is free spins feature. To force it you need to provide in tag ListStringData sequence of numbers:

featureId (0/1)

COMPONENTSET id

COMPONENTSWAP id (always 0)

So for instance to gaff / emulate base game set 5 you need to provide:

Gaff:

<DemoData>
    <Identifier>BaseGameReelStops</Identifier>
    <Description>Force reel set</Description>
    <StringData>Feature</StringData>
    <ListStringData>0 4 0</ListStringData>
</DemoData>

Emulation file: forcefeatures.txt

0 4 0

Custom Features

Rest of the features are custom made, however you can still gaff / emulate its results

In your demo entry you provide demo data structure, where

Identifier is ether BaseGameReelStops or FreeSpinReelStops_x (where x is freespin spin number, eg FreeSpinReelStops_1)
StringData is one of the following:

Pattern Trigger - feature responsible for lucky throwing coins on the screen
StringData: is PatternTrigger
IntData: 1 - means pattern will be triggered, 0 - pattern will not get triggered (and the rest of this entry will be ignored)
ListStringData (Optional ): list of numbers representing screen. Each ListStringData represents column (reel), so most likely you want to put 5 entries for each reel in the game. Each entry should have 5 numbers that represents rows. Each number may be one of the following:
- 0: coin will not land on this position
- 1: random coin will land on this position
- number greater than 1 - specific symbol id landing on this position. Note: it is up to you to put correct symbol. Game naturally will place only COR symbols, however you can (but shouldn't) by mistake force other symbols as well which may have unexpected result.
Following code will put random coins on the screen
Gaff:
```
<DemoData>
      <Identifier>BaseGameReelStops</Identifier>
      <Description>BaseGameReelStops</Description>
      <StringData>PatternTrigger</StringData>

      <ListStringData>0 1 0 1 0</ListStringData>
      <ListStringData>0 1 0 1 0</ListStringData>
</DemoData>
```

JackpotSymbolTrigger - it is responsible for forcing that game will try to put jackpot symbol (see math feature flow). If rest of the math conditions are not met symbol may still not appear on the screen. If you want to enforce this symbol on the screen I suggest to use PattenFeature or CORReplacement feature. Most common use of this feature is to actually prevent game from spawning jackpot symbol
StringData: JackpotSymbolTrigger
IntData: 0: means jackpot will not be put on the screen, 1: game will try to put jackpot on the screen / reel
```
<DemoData>
      <Identifier>BaseGameReelStops</Identifier>
      <Description>BaseGameReelStops</Description>
      <StringData>JackpotSymbolTrigger</StringData>
      <IntData>0</IntData>
</DemoData>
```
Emulation file: forcejackpotsymboltrigger.txt
```
0
```
FreeSpinsSymbolTrigger - works in very similar way as jackpot symbol trigger except it is responsible for game to try to spawn COR free spin symbol (see math feature flow). The symbol may still not appear on the screen if other math conditions are not met. Useful to make sure that this symbol will not get spawn
StringData: FreeSpinsSymbolTrigger
IntData: 0: means fs symbol will not be put on the screen, 1: game will try to put fs symbol on the screen / reel
```
<DemoData>
      <Identifier>BaseGameReelStops</Identifier>
      <Description>BaseGameReelStops</Description>
      <StringData>FreeSpinsSymbolTrigger</StringData>
      <IntData>0</IntData>
</DemoData>
```

COR Symbol Replacement feature – this is responsible for replacing CR_1 symbols on reels with specific prizes. It is useful if you want to trigger specific prize combination on the screen. Note: forcing symbols will force provided symbol, so it is up to you to make sure that you are forcing correct symbol
StringData: CORReplacement_x where x is reel Id (0-4)
ListIntData: multiple entries representing sequential CR_1 symbol occurrence on the reel (not on the screen). Those numbers create list that will be used to replace symbols. If there is less numbers than symbols on the reel this list will get looped for given reel until no more CR_1 symbols left
This example will force symbols 12, 20 and 19 on reel 1 (second reel). As a result all CR_1 will get replaced in order: 12, 20, 19, 12, 20, 19... You can combine it with forcing correct reel stops to get exact win that you want.
```
<DemoData>
       <Identifier>BaseGameReelStops</Identifier>
       <Description>BaseGameReelStops</Description>
       <StringData>CORReplacement_1</StringData>
       <ListIntData>12</ListIntData>
       <ListIntData>20</ListIntData>
       <ListIntData>19</ListIntData>
</DemoData>
```
Emulation file: forcecorreplacement.txt
```
1 12 20 19
```
Note: for emulation you will include all reels in one file in multiple rows. First number will determine reel id (0-4). Following example will emulate symbols on reel 0 and 3:
Emulation file: forcecorreplacement.txt
```
0 12 20 19
3 13 16 17
```
Boost trigger - this is only visual feature and does not affect end game result, however it may by useful for game testing to be able to force it. You can only force it to get triggered (make sure that you stop reels that have COR award) or not to be triggered.
StringData: BoostTrigger
IntData: 1: will force boost to be triggered, 0: will prevent boost from beeing triggered
```
<DemoData>
      <Identifier>BaseGameReelStops</Identifier>
      <Description>BaseGameReelStops</Description>
      <StringData>BoostTrigger</StringData>
      <IntData>0</IntData>
</DemoData>
```
Emulation file: forceboosttrigger.txt
```
0
```
Animation gaffs - one more visual gaff. You can trigger pre win and win animations for testing. Since it is not math feature - there is no possibility to emulate animations
StringData: AnimationTrigger
ListIntData: pre action animation id. -1: don't force, 0-4 force specific animation
ListIntData: action animation id. -1: don't force, 0-5 force specific animation
```
<DemoData>
      <Identifier>BaseGameReelStops</Identifier>
      <Description>BaseGameReelStops</Description>
      <StringData>AnimationTrigger</StringData>
      <ListIntData>0</ListIntData>
      <ListIntData>-1</ListIntData>
</DemoData>
```
