Lag in ATL transform script ,please help me.[Solve]

[Sirin]

Hi! everyone.

I want to use ATL to move displayable in the screen, but after use "Transform" statement my displayable move with lag(it seem like hiccups) while the transform is continue until the end of transform.

this my Transform code :

Code: Select all

transform unit_move(ox,oy,nx,ny,tm):
    xpos ox ypos oy
    linear tm xpos nx ypos ny

and this when i use it.

Code: Select all

# in game
    ox,oy = 100,50
    nx,ny = 300,100
    tm = 3
    ui.add('unit1',at=[unit_move(ox,oy,nx,ny,tm)])
    renpy.pause(tm)

i tried many way to fix it, use "config.image_cache_size = 30" ,"config.framerate = 50" , "renpy.free_memory()" , "renpy.predict()".

but...no anything change, I don't know what to do next to solve this problem.

Please tell me if it has another way to move a displayable(maybe use ATL or not).

p.s. my laptop that i coding this project is from 8 year ago.(and use software render)

Try the old way:

[xavimat]

Try adding

Code: Select all

subpixel True

to the transform.

thank for you help Xela,Xavimat. but both way can't solve my problem either.

but I found something that may cause this problem. while run my project I saw CPU usage up to 50%+, if CPU usage more than 30%+ before displayable with transform appear that cause a lag but if I wait until CPU usage drop near 0% transform run smoothly as I wish.but in real situation the player can't wait that long(about2-3sec).

I don't know this problem appear because of my laptop performance or not. or it doesn't cause any problem with current PC and laptop' performance.

p.s.in previous version of renpy(like 6.9.0) it can run this transform without any lag,that why I very curious new version has this problem.

A performance regression would seem like a bug. I'm interested now - wonder if something happened to pygame.

Could you put show screen _image_load_log then watch something is loading or not?

um...Nyaatrap-san I don't know how to do that because I'm a newbie with renpy.can you teach me how to see _image_load_log,I still have many thing to learn about renpy. ^_^

[Asceai]

Just that

Code: Select all

show screen _image_load_log

on a line in a ren'py script, e.g. after label start:

It will show you when images are loaded

Thank you Asceai!! I'll try and post the result in this night.

This's cap screen Image_load_log while I was testing Transform statement.


It has only one displayable and transparent_tile(default screen of renpy).
I'm worry about it if lag occur with merely few displayable(and if I add lot of displayable in full version I don't want to think what will happen )

this is script and config.(I tried both way that used ATL and old method that xela and xavimat told me)

P.S.If anyone try this way and transform's lag didn't occur please tell me,I'll conclude it that only because of my laptop's performance is not high enough to handle it.

There is no delay that I could see even with software rendering.

Do you have anything else after these lines of code? Ren'Py preloading images, so if you gonna show rather big image in next few lines of code then this might be the issue.

[nyaatrap]

Firstly, better not to use ren'py.free_memory. It reinforces whole caching process. Secondly, put renpy.predict out side of python block one sentence before. One line $renpy.predict is better and should be placed before the line "test".

[Sirin]

Sorry for my late.

Oh!! Thank Xela. That mean I don't worry about player's pc ,smartphone or anything else they have.

Thank you for your advise Nyaatrap.I'll fix it instantly.

I have some script and function that testing about battle screen after this line.




....after I move script and function out transform run smoothly as i want.(I think this is real problem)
Thank you so much Alex , Xela , Nyaatrap , Xavimat ,Asceai. You guy help me alot,Thank you



at least this's a gift for everyone(or may not be that worth,i'm not sure )
...she's one of main heroine from my current project....but it just still a doodle sketch.

[Asceai]

Aha, so preloading was getting you. Yeah, Ren'Py looks ahead to load images before you need them to keep things running smoothly, but occasionally that can screw you over.
You can try and fix this by using the _image_load_log and seeing what gets loaded during the transition, then renpy.predict()ing that image beforehand.

It's a great sketch. Love to see it when it's lined.
