Java3D game problem(about wall)?(urgent>"<)

I am developing a 3D shoot game which contain a 3D mase,but...why the wall is transparent when I run towards the wall?how can solve this problem?Moreover,I wonder how to run smoothiy in 3D game?

thats just a *tiny* bit too vague for us to help you.

What I think hes trying to say is that when he goes towards the wall it dissapears... thats probably becuase you dont have a polygon to cover that side as poloygons only have one side thats solid, if you look at it from the other side you see right through it.CoW

or perhaps the wall is getting too close to the camera, and is not being rendered because of the near clip plane.

There are a million possible causes from that explanation. We need more info.

Yeh, I am going to guess he's too close to it and seeing through to the other side.

As for running smoothly,I think he should just pray to because we have been

enlightened to the God given rule that "one never needs to optimize."

yep..I see through to the other side(only left-side and right-side wall )..

Anyway I want to run on the plane smoothly and dont want to see inside and behind the wall..

following is the suitation of my game:

| * | | |* * |

| * |/|* * |

| * |/| * * |

| *|/ \ * * |

| *| / \* * |

| * \~ \\* * |

|*_\__\__\ * * |

* is transparent

heres an idea, why don't you take a screenshot of the symptom, put it on some webspace somewhere, and link us to it.

If you've doublechecked that you're not actually inside the wall (that is, you stop before it), try lowering the near clipping plane distance so that the wall will always be farther from you than that.

sor...cant draw image in this forum...

anyway..left-side and right-side wall get this problem..

but I have solved this problem!!

"only enlarge all objects in my game!!!"

Actually,I want to know why enlarging all objects cannot cause problem of wall transparency?

If increasing the scale of the world fixed the problem, then the problem was almost certainly your near clip plane.

near clip plane?what mean?
