# manually written functions

## [define_custom_obj_fields](#define_custom_obj_fields)

Defines a custom set of overlapping object fields.

The `fieldTable` table's keys must start with the letter `o` and the values must be either `u32`, `s32`, or `f32`.

### Lua Example
`define_custom_obj_fields({ oCustomField1 = 'u32', oCustomField2 = 's32', oCustomField3 = 'f32' })`

### Parameters
| Field | Type |
| ----- | ---- |
| fieldTable | `Lua Table` |

### C Prototype
`N/A`

[:arrow_up_small:](#)

## [network_init_object](#network_init_object)

Enables synchronization on an object.

- Setting `standardSync` to `true` will automatically synchronize the object at a rate that is determined based on player distance. The commonly used object fields will be automatically synchronized.
- Setting `standardSync` to `false` will not automatically synchronize the object, or add commonly used object fields. The mod must manually call `network_send_object()` when fields have changed.

The `fieldTable` parameter can be `nil`, or a list of object fields.

### Lua Example
`network_init_object(obj, true, { 'oCustomField1', 'oCustomField2', 'oCustomField3' })`

### Parameters
| Field | Type |
| ----- | ---- |
| object | [Object](structs.md#Object) |
| standardSync | `bool` |
| fieldTable | `Lua Table` |

### C Prototype
`N/A`

[:arrow_up_small:](#)

<br />

## [network_send_object](#network_send_object)

Sends a packet that synchronizes an object. This does not need to be called when `standardSync` is enabled.

The `reliable` field will ensure that the packet arrives, but should be used sparingly and only when missing a packet would cause a desync.

### Lua Example
`network_send_object(obj, false)`

### Parameters
| Field | Type |
| ----- | ---- |
| object | [Object](structs.md#Object) |
| reliable | `bool` |

### C Prototype
`N/A`

[:arrow_up_small:](#)

<br />

## [network_send_to](#network_send_to)

Sends a packet to a particular player (using their local index) containing whatever data you want.

`dataTable` can only contain strings, integers, numbers, booleans, and nil

The `reliable` field will ensure that the packet arrives, but should be used sparingly and only when missing a packet would cause a desync.

### Lua Example
`network_send_to(localPlayerIndex, reliable, { data1 = 'hello', data2 = 10})`

### Parameters
| Field | Type |
| ----- | ---- |
| localPlayerIndex | `integer` |
| reliable | `bool` |
| dataTable | `table` |

### C Prototype
`N/A`

[:arrow_up_small:](#)

<br />

## [network_send](#network_send)

Sends a packet to all players containing whatever data you want.

`dataTable` can only contain strings, integers, numbers, booleans, and nil

The `reliable` field will ensure that the packet arrives, but should be used sparingly and only when missing a packet would cause a desync.

### Lua Example
`network_send(reliable, { data1 = 'hello', data2 = 10})`

### Parameters
| Field | Type |
| ----- | ---- |
| reliable | `bool` |
| dataTable | `table` |

### C Prototype
`N/A`

[:arrow_up_small:](#)

<br />

## [get_texture_info](#get_texture_info)

Retrieves a texture by name.

### Lua Example
`get_texture_info(textureName)`

### Parameters
| Field | Type |
| ----- | ---- |
| textureName | `string` |

### Returns
- [TextureInfo](structs.md#TextureInfo)

### C Prototype
`N/A`

[:arrow_up_small:](#)

<br />

## [djui_hud_render_texture](#djui_hud_render_texture)

Renders a texture to the screen.

### Lua Example
`djui_hud_render_texture(texInfo, 0, 0, 1, 1)`

### Parameters
| Field | Type |
| ----- | ---- |
| texInfo | [TextureInfo](structs.md#TextureInfo) |
| x | `number` |
| y | `number` |
| scaleW | `number` |
| scaleH | `number` |

### Returns
- None

### C Prototype
`void djui_hud_render_texture(struct TextureInfo* texInfo, f32 x, f32 y, f32 scaleW, f32 scaleH);`

[:arrow_up_small:](#)
