Hello

I have created a skysphere where a spaceship is flying inside, i added the controls, and it all works fine, but it feels like a toy, its absolutely not realistic

here is my controlling code:


how can i make this more realistic?

How do you mean the controls are unrealistic? Do you need inertia?

As an aside, I attempted modelling the solar system once, but never got around to finishing it, (so some bits don't work). If interested, you can download it from:

http://www.computechtenerife.com/solarsystem.rar (4.5MB)

The + and - keys aren't implemented, but you can move around by holding down the left mouse button.

Tracking is ON by default and can be toggled by pressing the T key.

well, at this moment im looking for a way to prohibit turning more then 45 degrees (so the ship cannot turn upside down)

and what is inertia?

Darkbasic MAD:

What on earth has this topic got to do with sprites?!

And, unless you've edited your post since I last looked at it, it's not so much a tutorial as a list of Sprite commands.

You need to take a look at the many tutorials on the forum and see what they do - give a command and explain in detail what each part of that command does. A good start, but not really a tutorial...

PresFox:

Inertia is where your ship moves in one direction and keeps on going when you take your 'foot off the gas'.

In space, there's no friction, so accellerating to a certain speed then turning off the power would result in maintaining that speed and direction even if you turned the ship in another direction.

Applying power in the new direction would move the ship in the new direction combined with the new one. Stopping involves applying the power in the opposite direction to the direction travelling.

Did you look at my solar system demo? It has inertia, but not the multi-direction type that I just mentioned.

i thought sprite controls might help to get the object to move but not tilt

I've released the source and media to my unfinished Solar System Demo if it's of any use to you. It's DBC code.

Did you get this sorted?

Looking at your code it looks like you've got a form or inertia/momentum included where your key stroke adds to an overall speed range. I normally set x and y ranges to say -10 to +10 and a key press simply increments or decrements the speed. That way trying to move in the opposite direction doesn't just stop your ship but gradually slows it down before turning.

Have you thought about gravity as well. Use a variable (as above) to constantly move the ship to the ground while your upward movement key negates this (ala Thrust, Oids or Virus on the Atari ST). Add in an acceleration variable so the longer the ship moves down the faster it falls (within a range). Gives a reasonable representation of gravity.
