Mixing languages and web player caching...

[Rod-Galvao1]

Hi All,

I have 2 doubts:

a) Is it possible to mix C# code with JS code in my project. I mean, with a “shared memory” mechanism between the mixed scripts?

b) If a user downloads a .unityweb build from a web page, will he have to download it again when he access the same page? In other words, does the webplayer has a cache/new version feature?

TIA,
R.

Anyone?

1 Yes, you can mix the languages and call each others funtions.

2 The caching is done by the browser, so it depends on the browser. But generally; yes it is cached.

Note:

@file:///Applications/Unity/Documentation/ScriptReference/index.Script_compilation_28Advanced29.html

Script compilation is performed in 4 steps:

1. All scripts in “Standard Assets”, “Pro Standard Assets” or “Plugins” are compiled first.

Scripts in one of these folders can’t directly access scripts outside these folders.

It is not possible to reference the class or its variables directly, but it is possible to communicate with them using GameObject.SendMessage.

2. All scripts in “Standard Assets/Editor”, “Pro Standard Assets/Editor” or “Plugins/Editor” are compiled first.

If you want to use the UnityEditor namespace you have to place your scripts in these folders. For example to add menu items or write custom wizards you have to place your scripts in those folders.

These scripts can access scripts from the previous group.

3. All scripts in “Editor” are compiled next.

If you want to use the UnityEditor namespace you have to place your scripts in these folders. For example to add menu items or write custom wizards you have to place your scripts in those folders.

These scripts can access all scripts in all previous groups. However they can not access scripts, in the last group.

This can be a problem when wirting editor code since you often want to edit scripts that are in the last group. There are two solutions: 1. Move the other script into the “Plugins” folder. 2. Take advantage of JavaScript’s dynamic typing. In Javascript you don’t need to know the type of a class to work with it. When using GetComponent you can just use a string instead of the type. You can also use SendMessage, which takes a string.

4. All other scripts are compiled last.

All scripts that are not in the folders above are compiled last.

All scripts that are compiled in this step have access to all scripts in the first group (“Standard Assets”, “Pro Standard Assets” or “Plugins”). This allows you to let different scripting languages interoperate. For example, if you want to create a Javascript that uses a C# script: place the C# script in the “Standard Assets” folder and the Javascript outside of the “Standard Assets” folder. The Javascript can now reference the C# script directly.

Scripts that are placed in the first group, will take longer to compile, since when they are compiled the third group needs to be recompiled too. Thus if you want to reduce compile times, move scripts that seldomly change into group 1 and scripts that change a lot into group 4.

Thanks AngryAnt. BTW I´m looking close your project Behave. Very nice work. Congratulations.

Addressed above, but yes, you can.

b) If a user downloads a .unityweb build from a web page, will he have to download it again when he access the same page? In other words, does the webplayer has a cache/new version feature?

Web player files are treated (by the browser) like any other web file. When the page loads for the first time the data file is downloaded to the browser’s cache. Subsequent page loads will use the cached copy unless it’s been cleared from the cache in which case it loads it again from the server.
