inkey and key 'end' memory error - 11/20/15 12:09

Hi,

Normally I would ditch inkey and try to find another solution, but since this is a long project which already uses alot of inkeys, I am trying to make the best of it.

Anyway now to my problem: I personally never use the 'end' key when editing textboxes in programs/games, but I noticed that for inkey it gives memory errors (W1516) saying CAT.
My quess would be that is cause I do:

Code:

str_cat(input_str,"                         ");  
inkey(input_str);

to have more space to type. And it doesn't seem to give any problems whatsoever (for like the last 3 months of testing) besides when using 'end' key .
Is there anyway to disable the 'end' key or to prevent this memory error?

tia

Mhh this dont helps?

inkey
...
}

dont understand why you are doing this .

Code:

//string off 255 spaces
	STRING* input=str_create("#255");
	inkey(input);
	while(1)
	{
		draw_text(input,0,0,COLOR_RED);
		wait(1);
	}

I always used inchar instead of inkey. Input can be checked and avoid whatever you want.

Code:

void fncModifyString ( STRING *str )
{
	char key[2];
	key[0] = NULL;
	key[1] = NULL;
	while ( 1 )
	{
		var nKey = inchar ( NULL );
		if ( nKey == 8 )
		{
			if ( !key[0] )
			{
				str_cpy ( str, "" );
				txtCursor->pos_x = panHscores->pos_x + MC_HIGHSCORE_BORDER_SIZE_X;
			}
			else
			{
				str_trunc ( str, 1 );
				txtCursor->pos_x = panHscores->pos_x + MC_HIGHSCORE_BORDER_SIZE_X + str_width ( str, fntHscores );
				int count = str_len ( str );
				while ( str_getchr ( str, count ) == 32 )
				{
					count -= 1;
					txtCursor->pos_x += str_width ( "t", fntHscores );
				} 
			}
		}
		else if ( nKey == 13 )
		{
			if ( str_len ( str ) == 0 )
				str_cpy ( str, MC_HIGHSCORE_NAME );
			break;
		}
		else if ( nKey == 27 )
		{
			str_cpy ( str, MC_HIGHSCORE_NAME );
			break;
		}
		else if ( str_len ( str ) > MC_HIGHSCORE_MAX_CHARS )
		{
			continue;
		}
		else if ( nKey < 32 )
		{
			continue;
		}
		else
		{
			if ( !key[0] )
			{
				str_cpy ( str, "" );
				txtCursor->pos_x = panHscores->pos_x + MC_HIGHSCORE_BORDER_SIZE_X;
			}
			key[0] = nKey;
			str_cat ( str, key );
			if ( nKey == 32 )
				txtCursor->pos_x += str_width ( "t", fntHscores );
			else
				txtCursor->pos_x += str_width ( key, fntHscores );
		}
	}
}

, how to get this working if you are using a global string?

globally initializing STRING* input_str = "#100"; doesnt work right when I am editing it with inkey and I have no extra space to write letters/numbers.

in_key overwrites the string and can not exceed the string length. It's also a internal wait, I assume it can not draw_x till the internal wait is terminated. But I don't understand your issue. I'll put it on my testing list for later today, if you haven't solved it by then.

EDIT- You code works fine... As I believed, it draw text as soon as you hit (enter) the termination key. Due to the loop, only a TEXT* object can show the active entry of the inkey.
My test code

Code:

STRING* input_me="#228";

///////////////////////////////
function main()
{
  vec_set(screen_size,vector(800,400,0));
  vec_set(screen_color,vector(50,1,1)); // dark blue
  vec_set(sky_color,vector(50,1,1)); // dark blue
  video_window(NULL,NULL,0,"My New Game");
  inkey(input_me);
  while(1)
  {
  	draw_text(input_me,50,50,COLOR_WHITE);
  	wait(1);
}

there's no need for global initialization .

Code:

//global level
STRING *glob_str;

//some function
void foo ()
{
     glob_str=str_create ("#100");
}

what I don't understand is when you write "extra space" , because if you initialize with #100 it means you have a string that can take 100 characters .

do you mean you want to write blank spaces in the string or do you mean you want to resize the string length?

I think your error from your first post is a access error. The internal loop and locking of the string.
Anyway use 2 strings , something like this...

Code:

STRING* str_ret="";
STRING* input_str="#256"

str_cat(str_ret,"                             ");
inkey(input_str);
str_cat(str_ret,input_str);
while(1)
{
 draw_text(str_ret,50,50,COLOR_WHITE);
wait(1);
}

Anyways I'm a bit confused and firing into the dark, so if I'm off track here. Sorry

Well I use the inkey to edit textboxes etc in the game. Before doing inkey I copy the current string of the textbox to the input string. But when I do that it seems to be byebye to the #100 / 100 characters of the input string.

Yes indeed, inkey is limited to the size of the string. If you change the sting size you clip inkey. But even more copying the textbox->characters into the input is pointless, as inkey, should start at the first character location and overwrite the whole string.

Code:

STRING* str_input;
STRING* str_temp;
STRING* str_flush_buffer="#100";
STRING* str_textbox[10];

function fill_textboxs()
{
  int I;
 for(I=0;i<10;i++)
    {
       str_textbox[I]=str_create("");
     }
}

function str_mod()
{
int int_str_len;

str_cpy(str_input,str_flush_buffer); // Clear the input
int_str_len=str_len(str_textbox[0]); // Find current len of textbox
str_cpy(str_temp,str_textbox[0]);    // move textbox into temp/ or use a textbox_dply[array size of textbox]
str_cat(str_temp,str_flush_buffer);  // add the maximun input len of white spaces
str_trunc(str_temp,int_str_len);     // cut textbox len of white spaces off end of temp
str_cpy(str_input,str_temp);         // fill the input text + white_space trunced to max 
inkey(str_input);                    // Edit text
str_cpy(str_textbox[0],str_input);   // replace text in texbox
int_str_len=str_len(str_textbox[0]); // degubbing only
}

Not sure how this works but it's an idea to work from

Re: inkey and key 'end' memory error - 12/01/15 13:19

lol, I think I found a really funny solution with your help Malice, doing this after having copied content of current textbox string and before doing inkey(...):

Code:

str_cat(input_str, str_flush_buffer); //add spaces
str_trunc(input_str, 1); //removes point of memory error

I am not sure if this is bulletproof though. I mean in the world of memory errors it would be best to not use it blindly. So far after some testing it seems good though.

LOl - That's how it works with my help more often then not. I spit fire blind ideas and smart people find something useful in it.
It is a odd solution, I'd love to hear jcl explain why it works and throws a error without.
