How to sync the ball of battle game

Question

Hello ShepHertz,

I have some problem on 1vs1 real-time game .

The game is like tennis,players need to hit the ball to the other side.

My question is that when I transfer data to the server on a moment someone hit a ball successfully,

 the ball will go through on the other mobile because of network latency,

is  there any wat to solve this problem?

thanks

Answer 1

Hi,

You can use basic maths to hide the latecny. There are techniques like Dead Reckoning that you can use. For example, while sending an update you can send UTC timestamp and velocity along with the position of ball. On the other side, you can then calculate the time difference and use the velocity to find the real position.

Thanks

Answer 2

sounds good,but is it make ball teleport suddenly?

if so , player may have no time to react.

can that way make ball smooth?

You can move the ball a bit faster to hide the teleport like effect.
