Tilengine-PSP is the PSP port of Tilengine.
Tilengine is an open source, cross-platform 2D graphics engine for creating classic/retro games with tile maps, sprites and palettes. Its unique scanline-based rendering algorithm makes raster effects a core feature, a technique used by many games running on real 2D graphics chips.

Thanks megamarc for writing such a portable and easy to read code.

• Written in portable C (C99)
• MPL 2.0 license: free for any project, including commercial ones, allows console development
• Cross platform: available builds for Windows (32/64), Linux PC(32/64), Mac OS X and Raspberry Pi
• High performance: all samples run at 60 fps with CRT emulation enabled on a Raspberry Pi 3
• Streamlined, easy to learn API that requires very little lines of code
• Built-in SDL-based windowing for quick tests
• Integrate inside any existing framework as a slave renderer
• Loads assets from open standard standard file formats
• Create or modify graphic assets procedurally at run time
• True raster effects: modify render parameters between scanlines
• Background layer scaling and rotation
• Sprite scaling
• Several blending modes for layers and sprites
• Pixel accurate sprite vs sprite and sprite vs layer collision detection
• Special effects: per-column offset, mosaic, per-pixel displacement, CRT emulation...
• Supports packaged assets with optional AES-128 encryption

• offload math tasks to vfpu
• add the special effects (per-column offset, mosaic, per-pixel displacement, CRT emulation)
• change graphics renderer from SDL1.2 to sceGU

You can also build the library from source. Tilengine-PSP requires SDL1.2 and libpng to build.

  make -f Makefile.psp

C samples for the PSP are located in Tilengine/psp_samples folder. To build them you need the pspsdk.

Once installed, open a console window in the C samples folder and type

> make

The following section shows how to create from scratch and execute a simple tilengine application that does the following:

1. Setup the PSP exit callback.
2. Reference the inclusion of Tilengine module
3. Initialize the engine with a resolution of 480x272, one layer, no sprites and no palette animations
4. Load a tilemap, the asset that contains background layer data
5. Attach the loaded tilemap to the allocated background layer
6. Create a display window with default parameters
7. Run the window loop, updating the display at each iteration until the window is closed
8. Release allocated resources

Create a file called test.c in Tilengine/psp_samples folder, and type the following code:

#include <pspkernel.h>
#include <pspdisplay.h>
#include <pspdebug.h>
#include <pspctrl.h>

#include <pspgu.h>
#include <pspgum.h>
#include <pspge.h>
#include "Tilengine.h"

PSP_MODULE_INFO("Example", 0, 1, 1);
PSP_MAIN_THREAD_ATTR(THREAD_ATTR_USER);

int main(int argc, char* argv[]) 
{
	  setupExitCallback ();
    
    TLN_Tilemap foreground;

    TLN_Init (480, 272, 1, 0, 0);
    TLN_SetLoadPath ("assets/sonic");
    foreground = TLN_LoadTilemap ("assets/sonic/Sonic_md_fg1.tmx", NULL);
    TLN_SetLayerTilemap (0, foreground);

    TLN_CreateWindow (NULL, 0);
    while (isRunning ()) 
    {
        TLN_DrawFrame (0);
    }

    TLN_DeleteTilemap (foreground);
    TLN_Deinit ();
    
    sceKernelExitGame ();
    
    return 0;
}

Tilengine is just a programming library that doesn't come with any editor, but the files it loads are made with standard open-source tools. Samples come bundled with several ready-to-use assets, but these are the tools you'll need to edit or create new ones:

• Source code: VSCode, Notepad++...
• Graphics, tiles & sprites: Aseprite, Piskel, Grafx2...
• Maps: Tiled Map Editor

These people contributed to tilengine:

@turric4an - the Pascal wrapper
@davideGiovannini - help with the Linux-x86_64 port
@shayneoneill - help with the OS X port
@adtennant - provided cmake and pkg-config support
@tvasenin - improved C# binding
@tyoungjr - LUA/FFI binding
