You need a line
level_load("yourlevel.wmb");
in your script.

Because all WED does when "starting" your level if you added a script is running the script.

when i look at the main script, then it already got this line: level_load(level_str);

and if i change it to: level_load(level.wmb);, then i still get the same black screen.

Muhsin, this question rather belongs into the 'Starting with Gamestudio' forum.
When you run your main script, maybe the camera faces a black wall, press [0] to move the camera around (WASD or arrow keys (?) and mouse). Add a Position to set a starting point for your camera.


EDIT (regarding Muhsin's post below): Muhsin, this does not seem to be an update related problem, please post your question in the forum that I've mentioned above. Thank you!

let me tell you what i did, then you can tell me what i did wrong:

first i started WED, then i clicked on "new level", then i added an cube and a model on the cube. then i saved and clicked on "map properties" and choose the "A6_Shooter_project" script. then i gave the model the bahavier: "PlBiped01". then i saved the level, clicked "build", then clicked "OK" and then clicked "run". then a new window opened, but the window only contained a black screen. if you understand what i'm trying to say ( sorry about my bad english )?

what did i do wrong?

I dunno, maybe you renamed it to some other name when saving it. You must not change the level name anymore after adding a template script. But following this link will certainly help you:

http://tutorial.3dgamestudio.net/

and don't post such problems here, post them in "Starting"!

ok, i will try that tutorial. thanks for the helps and sorry for my post here.

Contrary to some beginner's rumours, Gamestudio upgrades are of course always 100% compatible to their predecessors. We guarantee that all previously properly working projects will still work as before. All possible incompatibilites are mentioned in the update sheet.

BUT: The behavior can be different when there already was something wrong in the script before.

Some answers:

- GED does not start: Most likely caused by having old versions of the .c or .h include files in folders where they don't belong. Check for multiple copies, especially mtlFX.c in the code folder.

- Collision box is wrong: Check your code where you set it. If you can't find an obvious bug there, contact support with a test level so that they can look into it. Typical reasons of a wrong collision box are changing the entity scale or having entity frames with large size variations.

- Physics doesn't work - there's nothing changed with physics in this update. Again, if you can't see an obvious reason in your code, contact support with a test level.

- Bones rotate different - nothing changed here, they rotate just as before. Otherwise, see above.

- Particle_trail demo shows a horizontal stripe in the free version - we can't reproduce this here; does the stripe also appear when you remove the BEAM flag in the script?

If you think you found a real bug in this beta version, please contact Support or post a bug report.

I start to think you really belief this.
But if you take a look at the bug list you have to realize that updating the engine must end in broken projects in some cases.

Well, obviously not. There were only two cases ever where an official update indeed contained a serious bug and had to be pulled. Finding such bugs is the purpose of a public beta. So just relax, help our environment by saving Internet bandwidth, and leave such threads to people who have really something to remark about the update. Thank you.

- I forgot one question:

Particles are black -> is probably unrelated to the update. Check if the script sets a color, or a bitmap - and also check for wrong flags that aren't particle flags. If you can't find a reason, contact Support.

No need to become angry or rude!
I just try to help other users sharing my experience with updates - obviously not the way you want to read, but my experiences from about 5 years and ~20 finished projects (and many unfinished).
