STRING* in struct problem #291604 09/26/09 17:29 09/26/09 17:29

I defined a struct: Code: typedef struct { STRINGscript; MAPmap; } LEVEL; and initialized the STRING at the beginning: Code: LEVELlvl_K={script="#20";} Now, i want to copy something in it: Code: STRINGstr=str_create("hello"); str_cpy(lvl_K.script,str); When i try to copy it, the Engine says: Invalid Arguments. EDIT: When i add Code: lvl_k.script=str_create("#20"); before i copy something in it, the Engine doesn't give any errors and the string contains "hello". But text( Code: TEXT*txt_1= { pos_x=100; pos_y=100; layer=2; font="Courier#25b"; string=lvl_K.script; } ) still shows "#20". Not an empty contant of 20 characters, simply #20. Why? Help me!

Have no idea, but this example I made quikly, works perfect for me:

Code:

#include <acknex.h>

typedef struct LEVEL {
	STRING *script;
	var xyz;
} LEVEL;

LEVEL *testLvl = { script = "#20"; xyz = 0; }

void main() {
	
	//getting the string into the struct you have two options
	//ONE
	STRING *testStr = str_create("test-script");
	testLvl.script = str_create("#20");
	str_cpy(testLvl.script, testStr);
	str_remove(testStr);

	//TWO
	STRING *testStr = str_create("test-script");
	testLvl.script = testStr;
	
	wait(1);
	error(testLvl.script);
}

Maybe post a little bit more of the whole code!?

But now, you add a TEXT:

Code:

#include <acknex.h>

typedef struct LEVEL {
	STRING *script;
	var xyz;
} LEVEL;

LEVEL *testLvl = { script = "#20"; xyz = 0; }

TEXT*txt=
{
	pos_x=10;
	pos_y=10;
	flags=SHOW;
	font="Courier#25b";
	string=testLvl.script;
}

void main() {
	
	//getting the string into the struct you have two options
	//ONE
	STRING *testStr = str_create("test-script");
	testLvl.script = str_create("#20");
	str_cpy(testLvl.script, testStr);
	str_remove(testStr);

	//TWO
	STRING *testStr = str_create("test-script");
	testLvl.script = testStr;
	
	wait(1);
	error(testLvl.script);
}

And the TEXT shows "#20".

Seems like the TEXT doesn't refreshs the string... think you have to copy the new string into the TEXT-object after having some changes always: Code: #include <acknex.h> typedef struct LEVEL { STRING script; var xyz; } LEVEL; LEVEL testLvl = { script = "#20"; xyz = 0; } TEXT txtTest= { pos_x=10; pos_y=10; font="Courier#25b"; strings = 1; flags = SHOW; } void main() { //change the string in the LEVEL-struct STRING testStr = str_create("test-script"); testLvl.script = testStr; //apply new string to the visible TEXT-object str_cpy((txtTest.pstring)[0], testLvl.script); } http://www.conitec.net/beta/atext-string.htm

Thats why the first attempt gave you invalid arguments because the target string of str_cpy must be really a STRING, a char* wont work, it only works in functions were it does not matter if the argument is a STRING* or char*.
