The Lounge What is on Your Mind? Idea for a New Forum Front End Using Unity and SciFi Assets Post 303008404 by Neo on Friday 1st of December 2017 05:07:23 AM

I'm going to delay this new application development (VR/AR dev for the site using a gaming engine) for a while and concentrate on new forum features (mobile and desktop) for the next few months using the same old tools (CSS, Javascript, HTML, PHP).


PS: I had a bad experience with a scifi asset seller in the Unity Asset store yesterday. Some real ***hole sold a Unity scifi environment asset with errors. It was cheap, just around $25 USD; but it had errors when I installed it. Since I am busy I asked for a refund because of the errors and the develop hurled insults at me and then accused me of trying to steal his $25 asset. I was amazed at how small minded and "Trump-Like" the world has become.

Because of this bad experience, I am going to stop developing in Unity3D and C# for a while as stick to "normal" JS/CSS and PHP forum upgrades for now.

set_gfx_mode(3alleg4)                                             Allegro manual                                             set_gfx_mode(3alleg4)

set_gfx_mode - Sets a graphic video mode. Allegro game programming library. SYNOPSIS
#include <allegro.h> int set_gfx_mode(int card, int w, int h, int v_w, int v_h); DESCRIPTION
Switches into graphics mode. The card parameter should usually be one of the Allegro magic drivers (read introduction of chapter "Graphics modes") or see the platform specific documentation for a list of the available drivers. The w and h parameters specify what screen resolu- tion you want. The color depth of the graphic mode has to be specified before calling this function with set_color_depth(). The v_w and v_h parameters specify the minimum virtual screen size, in case you need a large virtual screen for hardware scrolling or page flipping. You should set them to zero if you don't care about the virtual screen size. When you call set_gfx_mode(), the v_w and v_h parameters represent the minimum size of virtual screen that is acceptable for your program. The range of possible sizes is usually very restricted, and Allegro may end up creating a virtual screen much larger than the one you request. Allowed sizes are driver dependent and some drivers do not allow virtual screens that are larger than the visible screen at all: don't assume that whatever you pass will always work. In mode-X the virtual width can be any multiple of eight greater than or equal to the physical screen width, and the virtual height will be set accordingly (the VGA has 256k of vram, so the virtual height will be 256*1024/virtual_width). Currently, using a big virtual screen for page flipping is considered bad practice. There are platforms which don't support virtual screens bigger than the physical screen but can create different video pages to flip back and forth. This means that, if you want page flipping and aren't going to use hardware scrolling, you should call set_gfx_mode() with (0,0) as the virtual screen size and later create the different video pages with create_video_bitmap(). Otherwise your program will be limited to the platforms supporting hardware scrolling. After you select a graphics mode, the physical and virtual screen sizes can be checked with the macros SCREEN_W, SCREEN_H, VIRTUAL_W, and VIRTUAL_H. RETURN VALUE
Returns zero on success. On failure returns a negative number and stores a description of the problem in allegro_error. SEE ALSO
