Best practices to build a world for a Top-Down aircraft shooter

Unity Engine

Hello,

I am designing a Top-Down aircraft shooter I want some help from the community on what are the best ways to solve the design problem of building Terrains for this type of game?

First the requirements:

  • The game is a Fighter Jet flying at a Max Speed of 1500 Km\h.
  • The levels are supposed to be 8 minutes long.

As long as the fighter jet has a Max Speed of 1500 Km/h I can asume that:

  • 1500 Km/h = 25 Km/m = 0.416 Km/s

This means the jet is crossing the terrain at a speed of 416 m/s that is 416 unity units per second, the terrain size is calculated in unity units. (1 unity unit = 1 meter).

That means I need a terrain of at least 25 * 8 = 200 Km long.

How to solve this riddle in unity terrrain system? I created 2 large terrains each with a size of 100K Square Kilometers. Created a game object representing a plane coded the speed at 416m/s
with transform.Translate(new Vector3(0, 0, 416) * Time.deltaTime);
I crossed the whole 2 terrain patches at 8 min.

Is this the right way to do it?

Anytime you get more than a few thousand units away from the origin you probably need to consider a floating origin approach. It’s always easier to consider this from the start rather than trying to hack it in later.

Thank you for the tip however I didn’t get what you mean,

I have strcutured the Camera movement likewise:

Doing this I move CameraParent and the Main Camera moves with it, the Cube represent the Jet aircraft as for now, my calculations above were right.

Now I am going to the next challenge clamp the movement of the airplane based on screen resolution.
