General Jo Engine Help / Re: "Couldn't reserve space for cygwin's heap, Win32 error 0"

« on: September 28, 2017, 08:28:49 am »

Something I found in the Internet:

This requires one to change the Virtual Memory settings under Win 7 (Control Panel\System and Security\System > Advanced Systems Setting). On the "Advanced" tab, click on the performance "Settings" button - select advanced tab, and click on the "Change ..." button. Enter a custom size value as follows:
Initial Size (MB) = Currently Allocated (shown at the bottom)
Maximum Size (MB) = Recommended (shown at the bottom)

Click on "Set" button, click "OK" and reboot PC to take affect

Hi, you can't play multiple sound on the same channel, but you can play 8 sounds on the same time using jo_audio_play_sound which plays the sound on the first available channel.

See documentation here:

Hi,

Restart your PC. It's a shared memory issue, but I can't fix it (not in my code)

Hey man was just wanting to say keep up the great work with Z-treme as its a dream come true for a die hard Saturn fan. Just as a heads up just got 80 new cd=r so if you need anything tested on real hardware im  up

I also have some old 650 MB CDs

Once in two the engraving fails, because they are over 15 years old

Jo Map Editor / Jo Map Editor 6.0 available

« on: August 31, 2017, 09:16:44 pm »

Hi,

I made a new update of Jo Map Editor with some bugs fixes

As usual : http://jo-engine.org/mapeditor/

Jo Map Editor / [TUTORIAL] How to create a tileset with Jo Map Editor 6.0

« on: August 31, 2017, 09:13:07 pm »

1) Update Jo Map Editor : http://jo-engine.org/mapeditor/

2) Launch Jo Map Editor and select the folder where your sprites are located:



3) Drag & Drop an image on the editor



4) Explode your image in tiles



Warning: width must be a multiple of 8 in the Sega Saturn



5) Now you can move each tile and also drag & drop another image or re-explode one tile



6) Export the tileset for the Jo Engine





This will generate a file with the coordinate of each tile (to include in your project):

Code: [Select]

/*
   Tileset generated by Jo Map Editor v6.0
*/

#ifndef __TILESETNEWMAP1_H__
# define __TILESETNEWMAP1_H__

/* 36 tiles */
static const jo_tile    TilesetNewmap1[] =
{
	{0, 0, 32, 32},
	{0, 32, 32, 32},
	{0, 64, 32, 32},
	{0, 96, 32, 32},
	{0, 128, 32, 32},
	{0, 160, 32, 32},
...

7) Export the whole image in TGA, BIN format or C source file (in our example, we use TGA)



This image must be saved in the "cd" directory of your project in order to be load later



That's it ! Now you can follow the code inside the tileset demo ("demo - tileset" folder) in the Jo Engine source code

Hope the will help you

Jo-Engine release / Re: Release 9.0

« on: August 31, 2017, 09:27:57 am »

You have 2 issues:

1) Line 122 in main.c

Code: [Select]

ii.type=0;

must be

Code: [Select]

obj_table[ii].type=0;

2) You have some static data on your code and the jo_engine is slightly bigger than before so you must reduce the size reserved for malloc like the shooter demo.

More, you don't use jo_malloc() so...

To do that, you just have to add the line bellow in your makefile

Code: [Select]

JO_GLOBAL_MEMORY_SIZE_FOR_MALLOC = 262144

Now it works perfectly

Bug fixed: http://jo-engine.org/download/

Don't change the framerate value today, because it will disappear for another option in the next release
