Reg Media Editor -> WebEngine

Anonymous — Tue, 13 Oct 2020 06:57:19 GMT

Hello ALL,

In Media Editor, while creating a Web Engine, there is an option to give the URL or local HTML file path. Here we normally hard-code the path of the HTML file.

Is there a possibility to give a relative path of the HTML file ( for example, “%TMP%/user/myHTML.html”) so that when I copy the *.vpb file to any machine and still the media editor works the same way without having to change the path everytime.

Thanks,

Raghavan

This should work for setting the file path next to the .vpb file

$VRED_CURRENT_PROJECT_DIR\mypath1\mypath2\myindex.html

Hi,

I am getting the following error when I tried it using VRED 2020.1

expandFilename: couldn't expand env.var VRED_CURRENT_PROJECT_DIR! Path: $VRED_CURRENT_PROJECT_DIR\this\is\relative\test.html

I could not get information about this variable VRED_CURRENT_PROJECT_DIR in the help.

How can I set this variable using python code?

Also, I would like to use my own environment variable. Can I do this?

For ex: I create a variable myTestVariable and assign it to a temp folder.

Then can I use this variable as you mentioned inside the WebEngine control. "$myTestVariable\myHTML.html"

Thanks,

Raghavan

@Anonymous You can set a window specific environment variable e.g. with a batch script:

set myTestVariable=%~dp0\this\is\relative

or in C# within process start:

_currentProcess = new Process(); _currentProcess.StartInfo.EnvironmentVariables["myTestVariable"] = "C:\\temp\\"

Afterwards you can use this in your scene e.g. with python

import os os.environ["myTestVariable"]

or in the media editor with

$myTestVariable

Attached, you can find a small example, where you should see a diffenrence if you double click on the test.vpb or if you double click the batch script.

Hint: You may have to change the VRED path in the batch.
