Python

[Jonnee]

Hello Age Builders!

My next age is coming soon. Creation works fine, but I need help in writing the python scripts.
Robert The Rebuilder gave me a script that opens a door after pressing a button. You can see it here. It works fine and I use it alot in my Jo'nae age.
Now I have to seek for your's assistance:
Somebody please may modify the script for me, so that I can open two doors with it after pressing the button? One door should slide down and the other door should slide up on the Z axis. (like the Bahro Cave door)
My python skills are not well enough for doing it by my own, and I don't want to ask Robert again for help. He's pretty busy with other things... B)
I would be very thankful.

And then I'd like to have another script:
In the Functionality Check Age are some pistons that slide up and down continuously. I checked the FuncChk01Clickables.py and also tried to modify the script for my own use, but did not have any success.
My idea is a floating rock in the sky that slides slow up and down. Just as a visual effect.
Who can write that script for me please, so that I can import it easily to the main python file? The rock should slide 10 seconds up, stay there for 3 seconds, then slide down in 10 seconds, stay there 3 seconds too and then it repeats the movement.

Phew... That's alot.
But ill will be worth your's assistance, because there's coming something really huuuuuge.

Thank you very much and have a good week!

Christmas came early this year, Jonee!

Here's the code to do what you asked; in this example, it is a modification of FuncChk01.py, which moves the piston in the same manner as your rock. I make use of the sin() function, in order to have a smooth start and stop.

Note: I only listed the functions that were necessary for accomplishing this, for brevity's sake. You can replace them in your own copy of FuncChk01.py to see the piston doing this; then you can borrow code from it and place it into your age's script.

Looking forward to seeing your new age!

[Jonnee]

Whow. That's overwhelming!
Thank you very, very much for reworking the script for me. I will try it as soon as possible.
First preview screenshots of the new age will follow soon too. You'll like them! Definitly. B)

Greetings from far away Berlin...

EDIT:
Screenshots are now available at the H'Uru forum.

Hello, Robert!

I tried it, but I get an error when I want to pack the files.

What does this mean and how can I avoid it?:

Out file not created
File "D:/Programme/Ubi Soft/Cyan Worlds/Uru - Ages Beyond Myst/Python/Src/FuncChk01.py", line 12
def __init__(self):
^
SyntaxError: unindent does not match any outer indentation level

[Drakmyth]

Wow, a question I can possibly answer

Instead of using curly braces ( { and } ) to determine hierarchy within code, or using keywords (end if, fi, end with, wend, etc.), Python uses indentation only. This means that if a line has even one too many/few spaces before it, it will choke. This is why it is strongly recommended to use the tab key instead of spaces, it guarentees things line up. I haven't seen the Python file so I couldn't tell you exactly where the error lies, but something right around that line in the code should be indented wrong, (probably only by one space). As for the ^ telling you where the error is, it is generally near (though not on) the correct line and almost never on the correct character.

The error unindent does not match any outer indentation level tells me that the end of a code block is misaligned, not the beginning. take something along the lines of this example.

Code: Select all

for (int i = 0; i < myArray.size(); i++)
    if (i <= 5)
        System.out.println("Hello World!");
   end if


Now this is actually a pretty bad example because this is written in an incorrect java/visual basic crossbreed to serve my purpose. See if you can follow me though.

The line for (int i = 0; i < myArray.size(); i++) is all the way against the left side of the screen; there are no spaces before it.
The line if (i <= 5) has 4 spaces before it, this would tell python that this is a new block of code nested inside the FOR loop (which, I believe, does need to be indented).
The line System.out.println("Hello World!"); has 8 spaces in front of it, showing that it is nested into the IF statement (in python I believe this is also necessary to indent).
The final line end if has 3 spaces in front of it. However, this line is supposed to indicate the end if the IF statement 2 lines above. Python does not actually have an "end if" command, it checks this by comparing the amount of spaces before the line. Since the "end if" line has 3 spaces and there are no lines above it indenting 3 lines, you get the unindent does not match any outer indentation level error.


Assuming that you are not unimaginably confused by now (which I think I would be if I read this), it becomes apparent that the problem is one of your lines is indented wrong. Double check to make sure every line has a partner line (a line with the same amount of beginning spaces). If one doesn't, that is probably what's causing the error and just add or subtract lines to get it to partner with the line it's supposed to.

EDIT:
I looked at the code posted above and I see it is all indented correctly. It may have been a problem with the copy/paste not aligning right. Same error, just letting you know. I also modified my example to be put in a code block so spaces are kept instead of using *'s.

[Jonnee]

Ahhh. nice. B)
Now I understand the meaning of that "outer indentation level".
But for me everything looks fine, don't see where the error is. Maybe I forgot a whole passage??
Still need help, don't get it running.... :rolleyes:

Jonnee:

Can you post a link to your age's .py file? Another set of eyes might be able to identify the problem.

Jonnee:

Thanks for posting it. To fix the compiler error, insert one more space before each "def ..." statement - for a total of three spaces. I tried it on a copy of Piston1.py that I made from your post, and it compiles.

[Jonnee]

Yes, it compiles now.
So... I just went to the JonaeHood to see how my three pistons move - but they don't do so. :blink:

Mmmhh, what did we forget?
I've created three different python files (Piston1, 2 and 3) and changed the names and values in it.
I've imported the files to my JonaeHoodObject.py and compiled all to my JonaeHood.py.

Code: Select all

# emacs-mode: -*- python-*-
from Plasma import *

.......

That's the procedure that worked everytime before.
Compiling works well and Elfview doesn't show me any errors.
Do the objects in the blender file need any properties?
