Hello,
I am new to the forum that I have already been browsing for a few weeks, I thank the author of this bookstore (SGDK) who opened the doors to me to programming on Megadrive in C Language, as well as all the participants / members of this forums that enrich this section of the forum, it helps a lot.

So I come to ask for help / advice for something I want to check.
I would like to track the value of a variable of type "int / s16" ingame to realize that it takes the values I want during a collision.

First, I managed to do it using multiple loop if (value == v) {VDP_drawTextBG (plan, "value = v"), x, y}. but it's long and not very clean.

In fact VDP_drawTextBG (), takes a "const * char" as a parameter and as my variable is an s16 that's a problem, there is indeed a FIX16toStr () function which converts an s16 to char * in the string.h file.
Is there a way to convert s16 to const * char?

It's resolved with sprintf(), I had not seen this function.

Code: Select all

char str_Region[2] = "0";

void RegionDisplay()
{
	sprintf(str_Region,"%d",indexReg);
	VDP_clearTextAreaBG(BG_B,15,10,2,1);
	VDP_drawTextBG(BG_B,str_Region,15,10);
}

Hi.

You can use Gens Kmod, open degug > messages.

In your code put:

Code: Select all

KLog_U1("test:", intVARIABLE);

Yeah GEns Kmod debugging is really more convenient than trying to display value on screen.
Don't forget to enable active debug feature in Gens KMod otherwise message logging won't work !
