[SOLVED] Getting started w/ Unigine

[paulo.maciel]

Hello,

 

I am new to Unigine and have been trying to build/run the Unigine sample Apps on Windows.

I am kind of disappointed that there isn't a single .sln file for all the sample Apps.  Furthermore, when I try to run a couple of apps that I had built (namely, Nodes, States, Objects), I run into the following errors:
 

. The executable can't find the files under data/core (e.g. fonts and png images).  Is there an environment variable that I need to set in advance?  I also read that all projects need to be built under the 'data' folder.  Do I need to first copy the samples to that folder? 

. It cannot find the unigine.cfg configuration file.  It looks under the current directory but no one was provided.  Is there a default 'unigine.cfg' that I could use?

. Some sample apps seem to require OpenAL but nowhere in the documentation I found instructioins on how to configure OpenAL to use with Unigine.  Any pointers?

 

Also, when compiling one of the samples, compilation failed to find SDL/SDL.h.  There is no SDL.h under the Unigine folder.

 

Any and all help will be appreciated.

Thanks,

 

Paulo

Also,

 

Getting the following messages when building the Objects sample:

 

Interpreter::load(): can't open "C:/UnigineSDK/source/samples/Api/Objects/data/u
nigine.cache" file
Engine::init(): can't load "core/unigine.cpp" system script
Shutdown

Thanks for the help.

If I borrow a unigine.cfg config file from another sample, I get:

Loading "C:/UnigineSDK/source/samples/Api/Objects/unigine.cfg"...

Unigine fatal error
Engine::init(): can't initialize filesystem
Shutdown
Press any key to continue . . .

 

Any ideas?  Do I have a bad installation?
Thanks,

Trying to build the debug version of the Unigine app (to see if I could debug into it) did not work.  I get:

C:\UnigineSDK>cd utils

C:\UnigineSDK\utils>build.py --component=engine --type=debug --bits=64

[ Engine: debug build, 64 bit]
        building main app...

Same when trying with scons:

C:\UnigineSDK>cd source

C:\UnigineSDK\source>cd app

C:\UnigineSDK\source\app>cd main

C:\UnigineSDK\source\app\main>scons_x64 double=1
Can't find SCons.

C:\UnigineSDK\source\app\main>

Use *.py files to run samples.

You can use makefile to compile samples:

make_x64 -f Makefile.win32

Ok, looking at the Python script, I am now using the following as command line parameters to run from DevStudio.

-data_path ../../../../ -engine_config ../data/unigine.cfg

This works, thanks.

 

If I try to build all samples with the Makefile, I get:

 

C:\UnigineSDK\source\samples>make_x64 -f Makefile.win32
Setting environment for using Microsoft Visual Studio 2008 Beta2 x64 cross tools.
Setting Unigine environment for Windows x64 platform.

Thanks for all your help.

Still can't run the samples.

Can somebody from Unigine please post the command line parameters for say the Objects sample.

I am using:

 

-video_app direct3d11 -data_path ../../../../ -engine_config unigine.cfg -console_command "world_load objects"

 

and I get:

 

Loading "core/properties/unigine.prop" 2 properties 0ms
Unigine~# editor_load
Parser::load(): can't open "Unigine.h" file
Parser::preprocessor(): can't include "Unigine.h" file
Parser::preprocessor(): can't load "objects.cpp" file
Interpreter::load(): can't open "objects.cpp" file
Loading "core/editor/editor.cpp" 1347ms

 

Thanks,

Paulo

Hi Paulo,

 

To launch Objects demo, please make sure that <SDK>/lib folder is exists in your system variable 'PATH'.

 

After that you can run Objects demo via simple console command (or you can make *.bat file):

• Objects -data_path ../../../../ -engine_config ../data/unigine.cfg -system_script ../data/unigine.cpp -console_command "world_load data/objects"

Thanks!
