Hello Forum,

I have a character controller, the code looks like this:


However, it doesn't climb any object that is higher than the player and if i am putting another object underneath the player object it falls down when i am pressing the key to move.

The second problem is that if it does not detect ground underneath it doesn't fall down by itself, only when i am pressing the key to move the player.

Thank You!

More info, i am here.

I'm not familiar with the PhysX plugin so I can't give specific advice. However, this bit of your code looked odd to me:



Is that what you intended?

yes, but are you intending to take the y position of the camera instead of the object as you do with x and z?

Yes because this is a one time code initilization. I also tested with object's position y (9000) still the same problem.

Hey MateiSoft, you may have misunderstood some of your character construction parameters.

Your character creation call indicates that the character is not allowed to climb anything higher than 1 unit or slopes higher than a 1.5 degree angle. As you may now understand, these settings are what you might use in a game of Super Bomberman, but I doubt your character will be climbing anything until you set the angle higher to say 45 degrees. Make sure the step limit is high enough to ensure your character can climb the desired height. Let us know if that works.

I must say that I am no fan of DarkPhysics character controllers; I much prefer the DarkDynamix or DIY solutions; however be sure to call the phy move character controller ObjectID, 0.0 command when no movement is required; this appears to be the DarkPhysics way of updating the character controller.
Good luck

Yes that worked with the slope limit, thank you. I am trying to understand now if that second problem is because of gravity setup or not i forgot if Dark Physics has gravity or not.

Well apparently phy move object objnum, 0,0 did worked on the falling thing but it has a very low falling speed.

Yeah it has a gravity command: PHY SET GRAVITY

You can find similar functions in the engine section of the command reference .CHM file. Since gravity is a global coefficient, it can should affect the character's falling speed; however Dark Physics does not work well with large units, items seem to move extremely slow even with extremely high values, proportionately you should keep all of your scalar physics values low in your game world small; perhaps with character height of say 1 to 10 units.

What about the units; how large is the player? Try making the world and the player small enough for the physics system to handle correctly. As I stated in my previous post, things appear to move slow when things are too large for the physics engine. This issue of world scale correlates to the limit of single floating point figures used by DarkPhysics.

I compared a big object near my player and a small one and it has the same speed sadly ...

Consider using another physics plugin like Dark Dynamix or one of the others which you can search for. Dark Physics is really good for rigid bodies and joints; but the other features seem limited.
