|
Adds function to internal run queue.
|
|
If queue is empty, function provided will be ran on next frame.
|
|
If not, function will run after all previous function will be executed over game frames.
|
|
Can be used for queueing functions which can be called ina burst on a single game frame
|
|
and are not timing critical, like broadcasting log messages.
|
|
In example above it will avoid net channel overflow and avoid data discard when using
|
|
`reliable = false` in net.Start
