Lean Loader - Load from the web or a cache

Hi there,
The major performance upgrades I was hoping to get was not possible because the main performance hitch is on the Unity side of decoding an image :-/, but I will try and make auto-stagger out calls like this so you won't get a hitch if calling a bunch of load calls. You can also call the next image on setOnComplete( then call the next image to be loaded)

 

I am sending you an updated version that will auto-stagger out the processing of the loaded images. If you want to adjust this throttle just set the value:

//LeanLoader.IMG_PROCESSING_THROTTLE=5f; // defaults to one but set to larger to space out image calls

Other people wanting the same update, I will make an updated version for the store soon!

 

Hello dentedpixel...

There is still an error in your hosted json feed...
Please check it... (I reported it months ago! See page1. You should see it in less than 30 seconds.)

There is a error/typo in your latest json feed. http://dentedpixel.com/assets/test_json.txt
It returns ...
"texture":"ttp://dentedpixel.com/assets/PrincessPiano.jpg"
(h from http is missing)
---
Thanks

 

Fixed the JSON on my server but another error... The scene... LoadJSON Example is still not working. Can you help me? I downloaded the asset again (today) from the asset store to check that I have the latest version. Thanks...


---UPDATE---
I found the second error... The upper quotation marks are also messed up in the json file...

 

Sorry about that! I have fixed the JSON now on the server

 

Dented,

I'm using 5.5 and just dowloaded your package. there are a couple of minor bugs, and one huge one to report.

Here's a video to speed things up for you

So, the biggest thing is that, when using cached files, your own examples are not working, nor are my own hello worlds. I tested this a few times by creating new projects, and simply running the provided examples. on first load, the images draw. on subsequent "loads" a gray box is drawn. in your example, i can push the purge cache button and the stuff will load from web and draw, but break again on next load. if i custom code things using the minimal example i get the same results. i managed to get a black drawing, as you see briefly, if i set the cache duration to int.max, then delete the cache via code - i dunno which one triggered it - but it seems permanent. Issues persist on compiled applications.

In the video you'll see a few minor things, like a missing script reference in an example, and a conflict if you use leantween and leanload in the same project. there's also the minor issue that the lloption setUseFile is not documented on your website.

i use leantween religiously. i'm stoked to have a project that needs something I can pay you for. let me know if i'm missing something boneheaded.

 

Hey there!

Thanks for letting me know, I think there was a conflict with LeanTween. I have fixed that and I will dm you the updated package (I'll also upload it to the asset store for others).

This asset hasn't been very popular so I haven't kept my eyes on it, so it's good to get some feedback.

Thanks! Glad you like LeanTween

 

IT WORKS!!!!!!! So, to help anyone else and negate concerns. The post with the video about caching problems was fixed... in about 2 hours. Very much appreciated, Dented.

What does ".setUseFile(true)" do?

 

Also, if you don't set a cache life is it automatically forever?

 

SetUseFile makes sure you use file storage instead of PlayerPrefs when possible (set to true by default)

Yup cache life is set to forever by default.

 

I really can't believe you are using playerprefs as a database. Just can't....

 

Haha, that is just for Web. It uses file storage by default otherwise.

 

Have you ever checked the data in playerprefs in editor with a tool like "Advanced Player Prefs"? After downloading images with lean loader, there are millions of entries in playerprefs. 3 entries for each image. You didn't even compact the 3 data into 1. After a certain number of images, the tool can't even display that many entries and errors out.

 

Hello dentedpixel,

I am developing a game for StandaloneWindows, in which I am using LeanLoader to download and cache some textures. I see that there is a performance drop in game because of downloading textures and saving them to my localDisk (As I am using cache and by default useFile is set to true). Is there any other way to cache rather than saving them in localDisk ? I doubt saving them in localDisk is the reason for performance drop (as I am downloading some 90 textures at a single shot, writing all those data into files in localDisk would be a performance hit)

And does LeanLoader does the loading and caching part asynchronously ? And can I know, what is IMG_PROCESSING_THROTTLE ?

 

Ha, I know!
This bobbed up in a google search for "download anad cache file at runtime" this is a pretty crazy solution, taking the binary data files and stuffing them into Player Preferences.
For future finders of this page , this is not the way - Application.persistentDataPath is here for you.

I can't vouch for it but this is a much more sensible looking solution - https://github.com/shamsdev/davinci/blob/master/Davinci/Assets/Davinci/Scripts/Davinci.cs
