Various bug fixes + Added is_game_paused() and more background music functions to lua (#93) 
Bug: DynOS models with animations cannot swap animations if they are
     loaded via lua (smlua_model_util_get_id and
     obj_set_model_extended).
Fix: DynOS_Actor_GetActorGfx takes a graph node instead of a georef,
     and checks for DynosValidActors graph nodes if georef is NULL.

Bug: The game can crash when calling obj_set_model_extended inside a
     HOOK_ON_OBJECT_RENDER hook.
Fix: The crash happens in smlua_model_util_load_with_pool_and_cache_id
     due to pool being NULL. If the game can't allocate an
     AllocOnlyPool object, use DynOS to generate the graph node.

Bug: warp_to_level and similar functions don't trigger HOOK_ON_WARP.
Fix: Call HOOK_ON_WARP hooks in DynOS_Warp_UpdateWarp and
     DynOS_Warp_UpdateExit after level and mario initialization.

Bug: The game sometimes calls HOOK_ON_OBJECT_RENDER hooks for
     unintended objects.
Fix: Initialize hookRender field to 0 when creating an object.

Bug: Actions can't apply gfx offsets to characters that have an anim
     offset (Waluigi, Wario)
Fix: Add m->curAnimOffset to gfx.pos[1] instead of setting it to
     m->pos[1] + m->curAnimOffset, except during the jumbo star
     cutscene.

Supported Functions








































manually written functions


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

🔼

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
standardSync bool
fieldTable Lua Table

C Prototype

N/A

🔼


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
reliable bool

C Prototype

N/A

🔼


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

🔼


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

Lua Example

djui_hud_render_texture(texInfo, x, y, scaleW, scaleH)

Parameters

Field Type
texInfo 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);

🔼


get_texture_info

Retrieves a texture by name.

Lua Example

get_texture_info(textureName)

Parameters

Field Type
textureName string

Returns

djui_hud_render_texture_interpolated

Lua Example

djui_hud_render_texture_interpolated(texInfo, prevX, prevY, prevScaleW, prevScaleH, x, y, scaleW, scaleH)

Parameters

Field Type
texInfo TextureInfo
prevX number
prevY number
prevScaleW number
prevScaleH number
x number
y number
scaleW number
scaleH number

Returns

  • None

C Prototype

void djui_hud_render_texture_interpolated(struct TextureInfo* texInfo, f32 prevX, f32 prevY, f32 prevScaleW, f32 prevScaleH, f32 x, f32 y, f32 scaleW, f32 scaleH);
