Syntax Error in renpy 7

[vera-vee]

Moving glitch.rpy into project folder and attempting to launch game presents a syntax error. I am unsure how to fix this, or if additional syntax errors present themselves after this line, since it stops trying to run upon reaching this issue.

I'm sorry, but errors were detected in your script. Please correct the
errors listed below, and try again.

File "game/glitch.rpy", line 13: invalid syntax
        def __init__(self, child, *args, randomkey=None, **kwargs):

Ah, yes, that's because it's PY3 argument syntax, it works in renpy 8+ only. I'll leave this issue open while renpy 7 still exists.

[vera-vee]

Aha! My apologies, then! Thanks for the heads up. It's probably worth updating, anyhow. Have a good one!

[Gouvernathor]

As a fix, you can have def __init__(self, child, *args, **kwargs) then randomkey=kwargs.pop("randomkey", None). I won't add it in the code because I find that py2 code ugly, but it should work the same.

I just tried this and still get a syntax error.

[Gouvernathor]

Can you post the exact syntax error you get ?

I suggest you read some basic python language information befre going too deep in game programming. The kwargs.pop line goes in the next line.

[TreeBobber1]

For me replacing the argument with the kwargs.pop line wasn't enough to make glitch.rpy work. At first I got this error

I removed an additional comma which solved that error but then that was followed by this one

I'm sorry, but an uncaught exception occurred.

With additional comma I mean the one here

            return Fixed(Transform(child, alpha=.0),
                         *lizt,
                         fit_first=True,
                         crop_relative=crop or False,
                         crop=crop and (0, 0, 1.0, 1.0), <- This one here
                         )

[Gouvernathor]

Yes, good catch, you need super(glitch, self). in that case. (See why I left out py2 ?)

[TreeBobber1]

Well, good news, that fixed that error. Bad news, new one popped up

[Gouvernathor]

Ah, that's because of the round. But it should be fixed in 7.5.3, check again after updating (otherwise you need to wrap the round calls in int).

[TreeBobber1]

The cast to int did it. Thanks!

Im sorry, but...

[Gouvernathor]

Read the messages above. This is only going to get worse with the latest updates I made, as I don't care about py2 support. Please upgrade to renpy 8.

[Kl1novich]

I make mod for ES(Everlasting summer) and can't update game to new versions renpy. I understand, you don't like py2, but if you help sovle my problem, i create video for russian/ukrainian people who wants use your glitch effect for ES. (People will not write with the same problem as me.)

P.s: I run Renpy 8.0.3 and it work.

[Kl1novich]

I tried to transfer the game and it seems to have done. I am not a master of renpai and python, but somehow I transferred the game to a new version. Now I have another problem.

After solving the problems, I will put in a master game with a new engine.

P.s: problem in line 38 because i tried get glitch effect on sprite(image)

[Gouvernathor]

It seems you passed a string where you weren't supposed to. Not really sure though. In any case it's a different problem, so open it in another issue with the full traceback.
