Physics functions

[tjheldna]

I need a ridged body object to have more friction with the ground and to bounce less. The functions that I'm after were in LE2. are there any such functions in Leadwerks 3?

 

SetBodyElasticity();

SetBodyDamping();

 

Many Thanks@

I don't know about unofficial, but official commands like that do not exist.

Seeing some physic problems or missing stuff, i suggested : Bullet physics.

 

I really hope after next big update, it could be a new suggestion point for some future LE3 evolution

Bullet, is ways better than Newton, it's open source, stable used in AAA games , and have continuous detection better than some others.

Although I too wish for better physics, I really doubt we will get a different physics engine. Josh has put.this up for discussion a long time ago. And although most people either suggested bullet or physx, josh went with Newton. Replacing the current physics engine will probably not happen since it is a massive undertaking and there are other priorities.

 

That said: Newton is also opensource and reliable and has been used in aaa games. Amnesia and penumbra might the most famous ones. I don't think Newton is the problem either. There are unsolved bugs and perhaps something has gone wrong with integration in to leadwerks 3.

as far as i know Newton was also used in LE2 and it wasn't bad. I think some bugs got already fixed in Leadwerks 3. The speedup after loading for example. I don't think the physic engine is the problem.

I haven't looked in the cpp headers, but perhaps some undocumented functions or members can be found.

 

@beo6. Le2 used newton 2 while Le3 uses newton 3.

i will release a simple cube physics playtest.

I played with it , and had the cube going throught walls playing with big linear force applied.

So nope continuous detection not as good as Bullet.

[AggrorJorn]

If the force is high enough and/or the object is small then you need to turn on swept collision. So have you tested bullet with leadwerks? If not, then.it is just like saying: this Mercedes has very poor acceleration, therefor Toyota is better.

[YouGroove]

Even put swept by code but object not so thin could go throught walls.

Newton can be a good choice, just that you can have bugs like any engine.
