Is there any way to parse to a specific tick as fast as ParseToEnd()?

[srjnm]

Right now I'm parsing to a specific tick using a for loop and ParseNextFrame()

f, err := os.Open(fileName)
if err != nil {
    log.Println(err)
}
defer f.Close()

r := dem.NewParser(f)

for r.GameState().IngameTick() < endTick) {
    _, err := r.ParseNextFrame()
    if err != nil {
	log.Println(err.Error())
    }
}

This code is really slow unlike using ParseToEnd().
Is there any alternative to this like,

• Start parsing from specific tick
• Move to specific tick without parsing anything and then ParseToEnd()

Hi @srjnm

Great question!

Basically I would never recommend using ParseNextFrame().

Instead you should

• A: use RegisterEventHandler() and UnregisterEventHandler()
• or B: handle events conditionally in your code based on if you are in the right tick

also, r.GameState().IngameTick() < endTick may not work, as the last tick from the header is often not correct

hope that makes sense

and just to clarify, ParseNextFrame() can never be as fast as ParseToEnd() as it gives different guarantees and therefore can't parse ahead of the event that is being handled
