Hurrican SDL Port

[Pickle]

Interesting that it fixed the graphical issues.

Also you could try without -DRGBA_5551, this converts all the images to 16 bit textures where without would otherwise been 32 bit.

I should probably fix the makefile to use GL2 by default. Most likely I was testing the ES portions at the time of checking it in.

OGL2 Hurrican - it works and heres how!

Thanks for the extra compilation info there Pickle! Thanks to that, I have now got Hurrican compiled, running and looking every bit as good as the Windows original under Ubuntu 12.04 (KXStudio) amd64!

It really didn't look too hot when compiled using the default linux target build options which I think caused it to use the EGL renderer, at least not here using the non-free nvidia driver. Now that its using GL2 it looks very slick indeed! Now I'd like to be even more verbose so others can check out this flagship FLOSS platform shooter more easily.

To configure Hurrican to use OpenGL 2 rendering instead of EGL when compiling it for 'desktop Linux' (STOP PRESS! This is the year of desktop Linux! ) such as Ubuntu or Debian running on a PC (ie a machine with a GL2-capable GPU and suitable driver), edit

hurrican-code/Hurrican/src/Makefile

Change the TARGET to linux and then alter the build options as such:

ifeq ($(TARGET),linux)

EXE := ../hurricanlinux
CCP := gcc
CC  := gcc
LD  := g++
RM  := rm -f

USE_EGL := no
USE_GL2 := yes

DEFINES += -DLINUX -DUSE_GL2 -DRGBA_5551

INCLUDES_OS := -I/usr/include -I/usr/include/SDL -I/usr/include/GL -I/usr/include/libmodplug

LDFLAGS := -g -lSDL -lGL -lSDL_mixer -lSDL_image -lmodplug -lX11

endif

The target should be linux. I think i need to more info for switching the renderer.
Basically you need to switch out the existing defined, include path, and LDFLAGS library with the following:

GL1:
Defines: -DUSE_GL1
Include: -I/usr/include/GL
Library: -lGL

GL1 ES:
Defines: -DUSE_GL1 -DUSE_GLES1 -DUSE_EGL_SDL
Include: -I/usr/include/GLES
Library: -lEGL -lGLES_CM (this name can vary according to the system)

GL2:
Defines: -DUSE_GL2
Include: -I/usr/include/GL
Library: -lGL

GL2 ES:
Defines: -DUSE_GL2 -DUSE_GLES2 -DUSE_EGL_SDL
Include: -I/usr/include/GLES2
Library: -lEGL -lGLESv2

Edit:
Turn these on when needed, these will include the required source files for these features. You had USE_EGL set to no and thats why you had missing refs to EGL_* calls.
USE_EGL := yes
USE_GL2 := yes

new Linux targets required?

In my last two Makefile examples, I neglected to mention I was also changing the TARGET directive to 'linux' too, of course.

As it stands, that is the only change I have been successful in making to the Makefile and having it build. Changing anything else just gives errors for me.

If a command line switch or in-game config menu option to switch renderer isn't planned then it would be nice to add some more targets to the Makefile ie linux-egl, linux-gl, linux-gl2 etc. maybe instead of just linux. I am of course presuming switching renderer will fix my GFX probs - I could be wasting out time?

Thanks Pickle!

Here's another config I just tried:

ifeq ($(TARGET),linux)

EXE := ../hurricanlinux
CCP := gcc
CC  := gcc
LD  := g++
RM  := rm -f

USE_EGL := no
USE_GL2 := yes

DEFINES += -DLINUX -DUSE_GL2 -DUSE_GLES2 -DUSE_EGL_SDL -DRGBA_5551

INCLUDES_OS := -I/usr/include -I/usr/include/SDL -I/usr/include/GLES2 -I/usr/include/libmodplug

LDFLAGS := -g -lSDL -lGLESv2 -lSDL_mixer -lSDL_image -lmodplug -lX11 -lEGL

GCC sez

defs to compile Hurrican for GL2?

I've already pasted the startup output of Hurrican with its default build options, which I believe chooses EGL - right? I'm not even sure about that.

I have only been successful in compling Hurrican with its default defines, every time I try and remove EGL or GLES it fails to compile.

My last attempt to compile Hurrican just for GL2 looked like this, and of course it fails:

ifeq ($(TARGET),linux)
EXE := ../hurricanlinux
CCP := gcc
CC  := gcc
LD  := g++
RM  := rm -f

USE_EGL := no
USE_GL2 := yes

DEFINES += -DLINUX -DUSE_GL2 -DRGBA_5551

INCLUDES_OS := -I/usr/include -I/usr/include/SDL -I/usr/include/libmodplug

LDFLAGS := -g -lSDL -lSDL_mixer -lSDL_image -lmodplug -lX11

endif

GCC cries:

I'm using the non-free NV drivers btw.

Can I set the renderer from the command line or must I recompile with specific defs? If so, what?

The main artifact I see are a few thin rows of pixels floating below platforms. I'll do a screenshot if switching renderer backend doesn't fix it.

The renderer API version is selected during runtime. Check out the readme in the source here section with important details:

Definitions:
  Platform Type
	PLATFORM_DIRECTX : Use the original directx code
	PLATFORM_SDL     : Use the new SDL/OpenGL code
	__WIN32__	 : Use on windows builds
  OpenGL Options:
  	EGL		 : see SDLPort/eglport.h
	USE_GL1          : Use the OpenGL 1.X code (fixed pipline)
	USE_GLES1        : Use the OpenGL 1.X code with ES compatible (requires USE_GL1)
	USE_GL2          : Use the OpenGL 2.0 code (programable pipline)
	USE_GLES2        : Use the OpenGL 2.0 code with ES compatible (requires USE_GL2)
	USE_PVRTC	 : Use ImgTec's PVRTC texture compression (only for PVR gpu's)
  Sound:
  	USE_MODPLUG      : Use the stable modplug code for music. (otherwise mikmod is used, which is known to have problems)
  	
  Other:
  	ENABLE_CONSOLE_COMMANDS : turns a console where commands can be entered
  	_DEBUG			: enables some debug output

I'd almost forgotten about Hurrican until today when I thought it was time to compile it and see if Pickle ever fixed the joypad support under Linux and indeed he did - exactly one year ago today as it turns out! What are the chances I'd try it again exactly one year after he implemented the one feature I wanted to see!?

I've compiled it under buntu 12.04 (KXStudio amd64) - I'm getting some visual artifacts but I'm not sure if I was running it in GL or GLES mode - must try playing with the options.

Might we be able to get Hurrican into Debian Pickle?

Thanks for bringing such a polished free game to Linux!

Thanks for trying and posting some feedback. The primary difference in rendering is choice between GL1 and GL2. The ES variant of either is not very much different from the normal desktop GL.

The only graphical issues ive heard of is lines between tiles or maybe an bad line in tile. You can find some ideas i had about it a couple post back. I havnt had the problem occur on any of my devices.

Its all open source so anyone can package it for debian, if thats what you mean ;-)

Great work Pickle! Good to play Hurrican with a joypad!
