# Definitions

### Instructions

An instruction is a set of information defined by one line. It's split by a **;** character, it allows the script to properly read the data. This kind of line will define how you creation will retexture. In the below example, this line will retexture the prim named **button**, with the texture **cc72eb07-b8cb-be03-8635-1ad5d9afa5fd** on the faces **1** and **2**.

```
button;texture;1,2;4f089cf2-3e75-fa5f-d5f3-2d49fe92553d
```

### Texture set

A texture set is a block of code in the .config script. It contains at least one name and one or multiples instructions. In the below example, this texture set is called `redSet` and contains 1 instruction.

```
-redSet
button;texture;1,2;4f089cf2-3e75-fa5f-d5f3-2d49fe92553d
```

## All instructions

### HUD

```
// This line define the name of your creation between the script.
// Remain this name simple. Be sure it's the same between .config and .config HUD

@myObject


// Since the version 3.1.2 of the HUD, the HUD can't be rezzed by default. If you
// want your customer to be able to rez the HUD, you need to add this line
// to your .config HUD data

allow_rez
```

```aspnet
// Add this line in your .config HUD to enable the DEMO feature for your store.
// Customers will be able to play with your HUD before any purchase.
// By setting 10, the HUD will apply the texture set abyss after 10 seconds
// of inactivity

timeout;abyss;10

// Or you can set multiple texture sets if needed.

timeout;lighton,abyss;10
```

```aspnet
// You can define ALL as prim name to apply to every prims in your object.
//   You can also define ROOT as prim name to target the root prim of the object.
// You can define ALL_SIDES as face to apply to every faces of your prim.

ALL;texture;ALL_SIDES;4f089cf2-3e75-fa5f-d5f3-2d49fe92553d



// You are able to set multiple faces, separate by a ,

ALL;texture;1,4,5;4f089cf2-3e75-fa5f-d5f3-2d49fe92553d
```

```aspnet
// You can define more than one instructions per set. 

-redSet

// You can modify the normal map of any prim/faces

// You can modify the Bump map or Shiny Map, see https://wiki.secondlife.com/wiki/LlSetPrimitiveParams#PRIM_BUMP_SHINY

button2;bump_shiny;ALL_SIDES;2;5


// You can modify the specular map of any prim/faces

button2;texture_specular;2,3,1;4f089cf2-3e75-fa5f-d5f3-2d49fe92553d


// To remove a normal map, you can use this line.

ALL;texture_normal


// To remove a specular map, you can use this line.

### Object

```aspnet
// Add this line to your .config to enable the option TouchToApply
// If enabled, customers will have to click their object before
// they are able to retexture it. It has a timeout of 60 seconds.

touchtoapply

// You can also add this line if you are making one HUD for multiple object.
// It will ignore the messages like
//   ERROR: There is no prim named `something` in your object.
