Unreal is a massively powerful game engine that puts performance and graphics first. It includes industry-grade VR tools that power some of the best high-end experiences on the market such as Robo Recall. That's why Unreal is the perfect tool to create your own VR experiences. A tutorial site dedicated to using C in Unreal Engine 4. This site is meant for game developers wanting to learn how to begin using c in UE4. A collection of my Unreal Engine 4 C Tutorials that I have created over the years. Includes a wide range of topics and concepts including a third person shooter, inventory system, project templates, and specific topics like using timers in C and many more! Oct 15, 2019  slua-unreal is unreal4 plugin, you can use lua language to develop game login and hot fix your lua code via this plugin, slua-unreal give you 3 way to wrap your c interface for lua, including reflection(by blueprint), c template and static code generation by a tool, meanwhile you can communicate with blueprint, call lua from blueprint, vice. I am a full-time programmer who is looking to sharpen my Unreal skills and this is a perfect pace for me. The instructor shows you how to find the answers you need when you are developing on your own, which is a MUST in Unreal development since the documentation can be a bit obscure. Unreal is a free-to-use game development engine used by AAA studios and indie developers worldwide. It can be complex beast to get into, but we break it down step-by-step Already know Unreal and want to learn VR or Multiplayer?

Unreal mode consists of breaking the 64KiB limit of real mode segments (while retaining 16-bit instructions and the segment * 16 + offset addressing mode) by tweaking the descriptor caches.

Usage

Unreal mode is usually recommended in the two following cases:

• You're trying to extend a legacy 16-bit DOS program so that it can deal with larger data and neither Virtual 8086 Mode, nor xms are suitable for your needs.
• You're trying to load something that will run in 32-bit mode which is larger than 640K (therefore you cannot load it in conventional memory) and you don't want to bother writing a protected mode disk driver yet, but you also want to avoid switching between real and protected mode to copy chunks from the conventional memory buffer into extended memory.

You still will not have full access to all physical RAM if you do not have the A20 Line enabled; all the 'odd' 1 MiB blocks will be unavailable.

Implementation

To do this, you need to set the descriptor cache's limits for your segment register(s) to any value higher than 64KiB (usually a full 4GiB (0xffffffff)).

In protected mode, bits 3-15 in the segment registers represent an index into the global descriptor table. That's why in the following code 0x08 = 1000b gets you entry #1 (entry #0 is ALWAYS a null descriptor).

When (in protected mode) a segment register is loaded with a 'selector', a 'segment descriptor cache register' is filled with the descriptor's values, including the size (or limit). After the switch back to real mode, these values are not modified, regardless of what value is in the 16-bit segment register. So the 64KiB limit is no longer valid and 32-bit offsets can be used in Real Mode to actually access areas above 64KiB (segment * 16 + 32-bit offset).

Big Unreal Mode

This won't touch CS.
Therefore IP is unaffected by all this, and the code itself is still limited to 64KiB.

Huge Unreal Mode

Huge Unreal Mode enables code over 64KiB. However, it is more difficult to implement as real mode interrupts do not automatically save the high 16 bits of EIP. Initialization is simple though, you just load a code segment with a 4GiB limit:

WARNING: this may not work on some emulators or some hardware.

Compiler Support

Smaller C

Dev C++ Unrealized

The Smaller C compiler supports unreal mode. It produces MZ executables for unreal mode (can be loaded with BootProg).

The code and the stack are to be located below the 1MB mark and the stack size is limited by 64KB (IOW, there's nothing unusual about CS:(E)IP, SS:(E)SP, it's a natural setup for MZ executables in DOS). The DS and ES segment registers are set to 0, so C pointers can work as flat 32-bit physical addresses and address data or memory-mapped devices anywhere in the first 4GB of memory.

The startup code of these executables performs the necessary relocation (there are only custom relocations and no standard MZ relocations, which may simplify loading of the executables) and sets up unreal mode before passing control to the equivalent of main(). See srclib/c0du.asm and other C/assembly code under srclib in the compiler source tree for how to write bits of assembly code for unreal mode (look for asm('inline asm code') under #ifdef __UNREAL__).

Dev C++ Online

You can try out unreal mode in DOS (e.g. in DOSBox, VirtualBox + FreeDOS) as the compiler fully supports the DOS + unreal mode combo in its C library. tests/vesalfb.c is a simple example of setting up a VESA graphics mode with the linear frame buffer enabled and drawing something on the screen in unreal mode.

For an example of an Unreal Mode bootloader implementation with Smaller C, look at FYSOS.
