How to create a Metric System?

[Birdman]

I was wondering if somebody did already worked with this?

 

What i need to define a way to measure, size of objects, speed, weight and other stuff.

 

How can i turn object sizes to meters or feet?

 

Same with speed, i can get the velocity vector, how could i define a real speed for objects in KM/h or M/h.

 

velocity = GetBodyVelocity(object,0);
speed = Length(velocity);

 

What about weight from mass?

 

Thanks a lot in advance.

Its arbitrary and relative. If you say 1 unit is 1m then as long as you base your scale on that 0.01 units is a centimetre, and 1000 is a km.. same for mass 1 mass unit in LE could be called kg .. if thats what you choose it to be and you scale accordingly. The values have no real value or comparison to real world values, only what you decide really.

Leadwerks uses the metric system already. 1.0 unit = 1 meter. To convert a velocity to Km/h, divide it by 1000.

In my game I take pretend every unit is 1m.

[Birdman]

Great, thanks for the info guys, 1 unit 1 meter sounds fine.

 

What about mass?

 

@Josh = I just checked the speed i got while driving varies from 0 to 9 or so, that is M per tick? In that case what would be the best way to turn this m/tick to m/h?

[Josh]

Meters per second.

[Birdman]

velocity = GetBodyVelocity(object,0);
speed = Length(velocity)*60*60/1000; // KM/h

 

What do you suggest to take as base for mass? 1 mass 1kg will result in very heavy stuff (say a car will be 900 mass or so isn't that a lot) i'm currently using 1.3 for a car.

[Road Kill Kenny]

As long as the forces you are applying are in metric and at the correct scale then yes. So for example a car of 900 mass would need a decent force to make it go... Just like in the real world.

Leadwerks uses the metric system already. 1.0 unit = 1 meter. To convert a velocity to Km/h, divide it by 1000.

 

Is this still valid for Leadwerks 3.0+ ? It should be written somewhere easy to find.

It really depends on your own interpretation. 1 unit might as well be 1000 meters if you are making a space game. Just use a standard that you are comfortable with.

Yes and no. I think some things like the character controller and physics work best within a given range, whatever that is. Navigation especially is very limited.
