1. None U3D question : what is and what for is this "bitwise operator" (&& || == etc).
2. Why are models in U3D limited to 300 models and other objects(when it exceeds
this number comes error : "unexpected error has occured").
3. When objects are in large scale appears graphical errors
(zig zag edges, half invisible objects etc), will it be fixed in 2.0?

3. this is because U3d uses 16 bit z buffering :U3D: 2.0 will use 32bit z buffering

&& (and)
|| (or)
== EDIT: Ops mixed the together, it should be the same as =

The rest you have to ask Dr.Best.

1: == is the same as = if it's used in an if statement. It's just a habit of me to use always == because if = would be used in an if statement in C++ that would mean something that differs fatally from ==.
What Despellanion said about && and || was correct. Usually these operators are used in if statements. If you replace && by the word and and || by the word or you should get the meaning.
For example this code
Code:
 
if((value1>value2 || value2>value3) && value1<value4 && value2<value4){
   // ...
}

would mean the following:
If value1 is bigger than value2 or value 2 is bigger than value3 and value1 is smaller than value4 and value2 is smaller than value, do something.

2: The 300 is a limitation of U3D 1.31. In U3D 2.0 this limit will be much higher. It shouldn't cause problems then anymore.

This is because of the polygon limit if it is so far away from the main character or camera it will not draw. This can be changed by editing the value "view" in the create event.

Uhm... I don't really get what you mean, but sherif's answer on point three was correct.

@Dr. Best

Under create there is a varible "view". Right...

In your demo this is set to 90.

If you make the number larger the farther you can see.

:huh: :unsure:

Umm... I'm confused because your confused on my statement that started with Dr Best confused, then me being confused because he is confused. Hope that clears it up.

I'm talking about when large models don't fully show up.

EDIT:

Dang it guys I'm sorry I ment the "Range Varible" The larger that number is the farther you can see.
