Is your bitmap really 160x161? If it's the case, it won't work as GPSDK expect 8 bytes boundary pictures in 16bits. Your bitmap should be 160x168. Btw: on my website at http://www.nekanium.com/gp32 you will find some 16 bit examples (look also in the tutorials). Oankali.

Hi Pea! You are doing a very good job with your GPDesktop. I didn't visit your website for a very long time and didn't know if you were working on your project. I'm glad to see that you are :) Some month ago someone told in a thread that we could join our efforts but as we don't think we have...

It's a C library to include a GUI in your apps. The app you have seen is just a demo to demonstrate the capabilities of the library. The kernel is almost stable but there is still a lot of work to do with the controls as all the basic controls I want to code are not implemented yet.

My GBAX 2005 submission can interest you. Here's a link of some screenshots I've posted on GP32Spain. The library is not finished but it is in a very advanced stage.

... or how smooth you want the animations of the game.

Yes, very polished. I like a lot this sort of games. My entry in this compo is like last year one, a coder related entry: another c library to implement a GUI in our apps or games (not finished, but in a good way). Not very useful for players, but I hope it will be for coders.

Perhaps the library I'm preparing actually will help you in coding these apps. It's a customizable GUI.

That's what I wanted to say. Usually I code for fun. It's better when you know that a lot of people will like what you do. But usually I code for myself, what I want and how I want.

I started programming on a Spectrum 48K with rubber buttons (in 1983?) and never had a QL. But when the QL was released I was certainly impressed of it's specs. I must admit that I know nothing about the programs that where published for this computer. But I don't understand why you are so...

Anybody has never mentioned the Sinclair QL. That one could also be emulated.

You are right. In my makefile I don't have any reference of it. But I can assure you that it works, as I sometimes change some flags and the compiler do react differently. Strange...

Here you can find some tutorials to setup devkitARM with the oficial SDK.

I've tried with VC++ and I get the good result, but with GCC I get the wrong result. Strange... And why don't you prepare your table in you source file and include it when you need it? Here you have for example my sin and cos tables I have prepared for my tests. maths.h #ifndef __maths_h__...

When you want to display a float, you must change the format in sprintf, use f: sprintf((char*)g_string, "%f",angle);

I agree with Dalto, it would be a lot more convenient, faster and easier and you wouldn’t need to recompile all the SDK if the makefile is prepared correctly. When I modify one of my SDK files, only this file is recompiled. It’s completely transparent to me. For the point 5, you could...

Look at this page: http://echellon.hybd.net/issues/5/articles/circle/sincos.htm I think it can be very helpful. Oankali.

I'm not really sure that it is what he wants as with this solution you loose the information of one dimension, and so, to be able to access any tile in the map, you must make the calculations yourself. I think a better solution for this case, if the map is always 32 tiles (height/width?) is...

I don't know with srand() but with the official Gamepark SDK, if you seed with this instruction GpSrand(GpTickCountGet()) at the beginning of the code, you get always the same result, even in real hardware. @Puck: pos si, little lapsus.

GP32 does have a real time clock. Look here By the way, I think the best moment to initialize the random seed with the tick count, is not when you start the program, as you will always get the same result. The best moment to do it, is after the player has pushed at least one button, and the...

If I've done the tutorial for VC 6++, it's because it's the one I use, I have tried Dev C++ a long time ago but wasn't satisfied by the results as I couldn't debug my programs. As I always say, the major benefit of using VC and the Gamepark SDK for Windows is the ability to compile and debug...
