determining future Determining orbital position at a future point in time

This might come of as a millionth-time award winner beginner question, but since I'm not familiar with either correct terms or designations, I'll put this question in my own language, since I'm not really sure what to search for in previously answered questions.

I am building a game where I simulate planetary orbits. These orbits are static and will not change, as expected. Up until now I have calculated these orbits with step-by-step iteration with gravity vectors, but the scale have grown beyond what is possible in real-time.

My question is therefore how I calculate the planet's position at a given time t $t$:

Known variables:

  • planet position at time 0
  • planet speed at time 0
  • planet direction at time 0

What I wish to know:

  • planet position at time t$t$

I've probably seen some fancy answers to this questions out there, but they are not very intuitive for someone with limited knowledge in astrophysics like me. Thank you for your patience with me!
