I have a friend (HurrrrHmmm) who wants to know what would be better for making 3d games (This is not to do with a scripting language), Java or Python?

Java:
-Faster
-Uses More Ram
-Most used more for 3d games/apps (has a big community too)
-More wrappers to C++ stuff (Like Ogre3d, Which is what I'm going to use for graphics)
-More difficult

Python:
-Slower (But can be sped up with the use of IronPython or Psyco)
-Uses less Ram
-Less used for 3d games (but does have a big community)
-Lots of wrappers (like Java, like the Ogre3d wrapper :D)
-Less difficult

I know this is basic info, but I'm finding really hard to choose between both of these languages! Any help?

Depends on what language you like most. Both languages have powerful engines with large community (JMonkeyEngine for Java and Panda3D for Python). Panda3D is actually a hybrid engine, it's written in C++ but Python is the main language for it. You could apply same thing to Java/Python - write your engine in Java, write your game in Jython. Although, writing an engine won't get you anywhere near the completed game, so you'd be better off just picking a language you like most, pick an engine and start coding.




It also depends on your programming style - Java forces object oriented style and is verbose, while Python is more of a hack scripting language brief in form.

What do you mean by that, (I don't really understand)?

compare some similar java and python code. Java has a lot of variable declarations, types, keywords while Python goes away with that in order to allow for quickly writing new code. http://pythonconquerstheuniverse.wordpress.com/category/java-and-python/ here you have some examples, it's a bit Python biased but still.

Basically, if you want to write a medium -to- large program, use java. If you want to write a small application, use python. The speed hit in python will kill you on any decent sized application, and bug checking in python will get painful because of its dynamic typing.

So, it really depends what type of 3d game you want to create. Small game, use python. Medium to large game, use Java.

... So? The quantity of declarations and keywords does not a good language make.

Even with this definition of "hack scripting language", you haven't done anything to prove that it is good or bad.

What if I used various C++ libraries with python (like ogre3d, bullet, openal etc. and compiling to machine code with psyco)? Could this be suitable for a medium - large scale game? Or would Java still be better?

The term large is relative, but If you want to do any large games, do not use python --use Java. Or, better yet, use c++. But, if your choices are Java or python only, definitely use Java over Python. Even with c++ libraries that python uses --it will help, but Python is slow compared to Java..

this is older, but its one of the links I found

It depends on the type of game, and your definition of "medium" and "large". Action games are far more performance sensitive than turn based games.

Python has been used in large AAA games, but mostly as a scripting language for the non-performance sensitive aspects of the game. If you are using libraries for graphics and physics you might be able to get away with using Python for most everything else.

There is no right answer. What you need to balance are the requirements of your game, and your own requirements in terms of productivity and experience in the languages you know.

      Hi fellow game devs,
      First, I would like to apologize for the wall of text.
      As you may notice I have been digging in vehicle simulation for some times now through my clutch question posts. And thanks to the generous help of you guys, especially @CombatWombat I have finished my clutch model (Really CombatWombat you deserve much more than a post upvote, I would buy you a drink if I could ha ha). 
      Now the final piece in my vehicle physic model is the differential. For now I have an open-differential model working quite well by just outputting torque 50-50 to left and right wheel. Now I would like to implement a Limited Slip Differential. I have very limited knowledge about LSD, and what I know about LSD is through readings on racer.nl documentation, watching Youtube videos, and playing around with games like Assetto Corsa and Project Cars. So this is what I understand so far:
      - The LSD acts like an open-diff when there is no torque from engine applied to the input shaft of the diff. However, in clutch-type LSD there is still an amount of binding between the left and right wheel due to preload spring.
      - When there is torque to the input shaft (on power and off power in 2 ways LSD), in ramp LSD, the ramp will push the clutch patch together, creating binding force. The amount of binding force depends on the amount of clutch patch and ramp angle, so the diff will not completely locked up and there is still difference in wheel speed between left and right wheel, but when the locking force is enough the diff will lock.
      - There also something I'm not sure is the amount of torque ratio based on road resistance torque (rolling resistance I guess)., but since I cannot extract rolling resistance from the tire model I'm using (Unity wheelCollider), I think I would not use this approach. Instead I'm going to use the speed difference in left and right wheel, similar to torsen diff. Below is my rough model with the clutch type LSD:
      speedDiff = leftWheelSpeed - rightWheelSpeed; //torque to differential input shaft. //first treat the diff as an open diff with equal torque to both wheels inputTorque = gearBoxTorque * 0.5f; //then modify torque to each wheel based on wheel speed difference //the difference in torque depends on speed difference, throttleInput (on/off power) //amount of locking force wanted at different amount of speed difference, //and preload force //torque to left wheel leftWheelTorque = inputTorque - (speedDiff * preLoadForce + lockingForce * throttleInput); //torque to right wheel rightWheelTorque = inputTorque + (speedDiff * preLoadForce + lockingForce * throttleInput); I'm putting throttle input in because from what I've read the amount of locking also depends on the amount of throttle input (harder throttle -> higher  torque input -> stronger locking). The model is nowhere near good, so please jump in and correct me.
      Also I have a few questions:
      - In torsen/geared LSD, is it correct that the diff actually never lock but only split torque based on bias ratio, which also based on speed difference between wheels? And does the bias only happen when the speed difference reaches the ratio (say 2:1 or 3:1) and below that it will act like an open diff, which basically like an open diff with an if statement to switch state?
      - Is it correct that the amount of locking force in clutch LSD depends on amount of input torque? If so, what is the threshold of the input torque to "activate" the diff (start splitting torque)? How can I get the amount of torque bias ratio (in wheelTorque = inputTorque * biasRatio) based on the speed difference or rolling resistance at wheel?
      - Is the speed at the input shaft of the diff always equals to the average speed of 2 wheels ie (left + right) / 2?
      Please help me out with this. I haven't found any topic about this yet on gamedev, and this is my final piece of the puzzle. Thank you guys very very much.

      Kepuh's Island is Multiplayer 3D Survival Game where you survive on the Kepuh's Islands, confronting challenges that are not only other players but also bosses, and even the environment itself.
      We have a lowpoly faster battle-royale idea, where about 12 players on the map fighting for survival! Also adding some more things into that style such as bosses around the map giving you abilities and much more such as vehicles, weapons, skins, etc...
      Now we are on cartase which is a crowdfunding online which purpose is to raise funds for the development of the game. Come and be part of this development.
