Defined in: gateway/src/manager.ts:870
Used to request soundboard sounds for a list of guilds.
This function sends multiple (see remarks) Request Soundboard Sounds gateway command over the gateway behind the scenes.
Parameters
guildIds
The guilds to get the sounds from
Returns
Promise
<void
>
Remarks
Fires a Soundboard Sounds gateway event.
⚠️ Discord will send the Soundboard Sounds for each of the guild ids however you may not receive the same number of events as the ids passed to Request Soundboard Sounds for one of the following reasons:
- The bot is not in the server provided
- The shard the message has been sent from does not receive events for the specified guild
To avoid this Discordeno will automatically try to group the ids based on what shard they will need to be sent, but this involves sending multiple messages in multiple shards

https://discord.com/developers/docs/topics/gateway-events#request-soundboard-sounds

shardsFullPercentage
shardsFullPercentage:
number
The % of how full a shard is when resharding should be triggered.
Remarks
We use discord recommended shard value to get an approximation of the shard full percentage to compare with this value so the bot may not reshard at the exact percentage provided but may reshard when it is a bit higher than the provided percentage.
For accurate calculation, you may override the checkIfReshardingIsNeeded
function

spreadShardsInRoundRobin
spreadShardsInRoundRobin:
boolean
Defined in: gateway/src/manager.ts:625
Whether to spread shards across workers in a round-robin manner.
Remarks
By default, shards are assigned to workers in contiguous blocks based on shardsPerWorker. If any shard is left over, it will be assigned to the last worker. This means that if you have 3 workers and 40 shards while shardsPerWorker is 10, the first worker will get shards 0-9, the second worker will get shards 10-19, and so on, the last worker will get shards 20-39.
If this option is set to true, the shards will be assigned in a round-robin manner to spread more evenly across workers. For example, with 3 workers and 40 shards, the first shard will go to worker 0, the second shard to worker 1, the third shard to worker 2, the fourth shard to worker 0, and so on.
Default
false
Inherited from
Required.spreadShardsInRoundRobin
