guvacode / ray4laz

A complete header translation (binding) of the raylib 5.0 to Pascal. Without any funky helper functions for memory alignment issues. Inspired and partially based on the drezgames/raylib-pascal binding, however a little cleaner and more recent, with FPC 3.2.0 and up support.

Ray4Laz is a header translation of the Raylib Game Development Library for the Lazarus project.

raylib is a simple and easy-to-use library to enjoy videogames programming.

raylib is highly inspired by Borland BGI graphics lib and by XNA framework and it's specially well suited for prototyping, tooling, graphical applications, embedded systems and education.

*NOTE for ADVENTURERS: raylib is a programming library to enjoy videogames programming; no fancy interface, no visual helpers, no auto-debugging... just coding in the most pure spartan-programmers way.*

building raylib on multiple platforms

raylib Wiki contains detailed instructions on building and usage on multiple platforms.

• Working on Windows
• Working on macOS
• Working on GNU Linux
• Working on FreeBSD
• Working on Raspberry Pi
• Working for Android
• Working for Web (HTML5)
• Working anywhere with CMake
• CMake Build Options

installation in lazarus ide.

select the package menu, open the network package manager.

select ray4laz package and install.

create a new project (Ray Simple Project).

enjoy !!!

manual installation and use without lazarus ide

clone this repository, then use 'fpc-wrapper.sh' as your compiler. this script automatically feeds fpc with the necessary arguments.

ray4laz's Issues

GuiTextBox partialy functioning

Hi Guya,

If the array of chars variable that is passed to GuiTextBox is attributed a value other than initializing it with '', outside the GuiTextBox, then this one will not allow editing the content of that variable. The following example works well, you can edit that variable as you like:

eText : array [0..60] of char = '';
iCategoryInput := GuiTextBox(rec_common, @eText, 60, true);

But if I touch the eText variable in any way, GuiTextBox will show its content but will not allow the editing;

These attributions:

eText := 'Spasiva!';`

or

eText := another_string_variable;

then eText is rendered non-editable in GuiTextBox, no matter if fpc is at 3.0.4 or 3.2.2 version.

I think (if is working the same also on your side) at least GuiTextBox must be rewritten in pascal.

I work at a visual demonstration program for qdbm database engine, in the way the example from fpc package is made for sqlite3 by ...pork... (can't remember his nickname), and I use raylib 4 with raygui from your translation.

raylib window context to OpenGLControl (initial code)

• Requirements:
  • GLFW for Free Pascal/Lazarus
  • DLL etc.
• Docs:
  • raysan5/raylib#1216

Still working on this, but the rendering happens in the TOpenGLControl on the form.

uses
OpenGLContext, raylib, glfw, Windows;

  TPortFrm = class(TForm)
    OpenGLControl1: TOpenGLControl;
    procedure FormCreate(Sender: TObject);
    procedure OpenGLControl1Paint(Sender: TObject);
  private
    WndContext: pGLFWwindow;
  public

  end;

procedure TPortFrm.FormCreate(Sender: TObject);
begin
  InitWindow(1600, 900, 'port');
  SetTargetFPS(60);
  WndContext:=glfwGetCurrentContext();
  OpenGLControl1.Handle:=HWND(WndContext);
end; 

procedure TPortFrm.OpenGLControl1Paint(Sender: TObject);
begin
  while not WindowShouldClose do begin
    BeginDrawing;
    ClearBackground(RED);
    OpenGLControl1.SwapBuffers;
    EndDrawing;
  end;
end;

Any chance to have the header? We compile the C library ourselves. Thank you!

How easy would it be to make a basic Lazarus game editor with this?

Basic lighting example is black

Box and plane are black in shaders_basic_lighting. How do I fix them? I use Windows.

iqm animation/DrawModelEx spinning bug

When loading an animation and using DrawModelEx the model keeps pivoting around its root position. When I use DrawModel and DrawModelWiresEx the model stays where it should.

Thanks

Delphi support

Is it possible to add Delphi support in header files?
I looked code and i think, this solved by a small number of IFDEF'S.

Unable to Run

Windows 10 x64
Lazarus 2.2.0RC2 (built via fpcupdeluxe)
OPM: Installed Ray4Laz

Receiving "raylib.dll not found..." error. Rebuilding ray4laz_designtime v.4.0 removes this error. However, I still get the "Execution stopped with exit-code 1073741515" error. See screenshots for specific error messages.

Admittedly, this may be completely user error. Nonetheless, your work is invaluable and in the event someone else might get this fringe error it may be worth documenting.

How to run without Lazarus?

I am tired of Lazarus, and I would like to use just vim and fpc.

What flags do I need to link with Ray4Laz?

BindPose/FramePoses Rotation not working

Anyone else experiencing this issue on Windows? Any leads on what might be the culprit?

How to publish as apk

How to publish as apk

Nothing works

Installed through package manager. Load examples.
If there is not some error like:
models_animation.pas(31,40) Error: Call by var for arg no. 1 has to match exactly: Got "Pointer" expected "TMaterial"
ray_header.pas(1270,11) Hint: Found declaration: SetMaterialTexture(var TMaterial;LongInt;TTexture); CDecl;

Then the example compiles, runs, exits without anything ever showing up on screen.

Same with the program template from the file> new menu.

Move examples to a separate repo

When there are loads of examples (especially huge ones) in the repo, it significantly slows down the process of git-cloning it.

Would be good to move them to a separate repository and add a mention in the README about it.

android platform

Hi
is it possible to support android ?
