Panel and Button - 04/11/09 13:21

I'm using Bloodshed Dev-C++ for C++ using A7 engine (version 7.06.1).

Showing panels itself is no problem, but I don't know how to implement buttons into them. When I try to implement button into my panel, both bmap and button give me an error that they are undeclared.

I tried all variations of buttons and different ways of putting them:
button_toggle(_VAR(0), _VAR(0), resume0_bmp, resume0_bmp, resume1_bmp, resume1_bmp, NULL, NULL, NULL);
and
button_toggle = _VAR(0), _VAR(0), resume0_bmp, resume0_bmp, resume1_bmp, resume1_bmp, NULL, NULL, NULL;

This is part of my codes (there are no functions inside my button, it is still in testing phase):

Code:

BMAP* resume0_bmp = bmap_create("button_resumeOut.bmp");
BMAP* resume1_bmp = bmap_create("button_resumeOver.bmp");
PANEL* pause_pan;

void loadHUD()
{
   pause_pan = pan_create("bmap = screen_pause.tga;", _VAR(2));

   pause_pan->pos_x = _VAR(373);
   pause_pan->pos_y = _VAR(197);
   pause_pan->flags |= OVERLAY | TRANSLUCENT;
   button_toggle(_VAR(0), _VAR(0), resume0_bmp, resume0_bmp, resume1_bmp, resume1_bmp, NULL, NULL, NULL);
}

void engine_init()
{
   ev = engine_open(NULL);
   SETV(video_mode, 8);
   SETV(max_particles, 20000);
   SETV(max_entities, 2000);
   SETV(fps_max, 60);
   SETV(ph_fps_max_lock, 60);
   SETV(shadow_stencil, ON);

   ...

   loadHUD();

   ...
}

Creating it using this method doesn't give any error on compiling but crash while running.

Code:

PANEL* pause_pan = pan_create("bmap = screen_pause.tga; pos_x = _VAR(373); pos_y = _VAR(197); button_toggle(_VAR(0), _VAR(0), resume0_bmp, resume0_bmp, resume1_bmp, resume1_bmp, NULL, NULL, NULL); flags |= OVERLAY | TRANSLUCENT | INVISIBLE;", _VAR(3));

Anyone know what is my problem? How can I solve it?

I have no idea about the problem. But, try to update your Gamestudio.

Your BMAPs are declared incorrectly for globals.

You would use this syntax if you were declaring LOCAL bmaps (INSIDE a function),
BMAP* resume0_bmp = bmap_create("button_resumeOut.bmp");
BMAP* resume1_bmp = bmap_create("button_resumeOver.bmp");

But you are defining GLOBAL bmaps (OUTSIDE a function), so you need to use
BMAP* resume0_bmp = "button_resumeOut.bmp";
BMAP* resume1_bmp = "button_resumeOver.bmp";

Its weird I know, but thats how it goes....

[EDIT] Sorry, just remembered you are using C++, not lite-c.

Thanks, EvilSOB, will try that nevertheless.

EvilSOB > I can't use your method, it will say it "cannot convert from to BMAP*"

Anyway, my main problem is with the button, any other suggestion?

This is largely educated guessing but try this.
WARNING - requires 7.71

Code:

BMAP  *resume0_bmp, *resume1_bmp;
PANEL *pause_pan;

void loadHUD()
{
   resume0_bmp = bmap_create("button_resumeOut.bmp");
   resume1_bmp = bmap_create("button_resumeOver.bmp");
   pause_pan = pan_create("bmap = screen_pause.tga;", _VAR(2));
   pause_pan->pos_x = _VAR(373);
   pause_pan->pos_y = _VAR(197);
   pause_pan->flags |= OVERLAY | TRANSLUCENT;
   pan_setbutton(pause_pan, _VAR(0), _VAR(2), _VAR(0), _VAR(0), resume0_bmp, resume0_bmp, resume1_bmp, resume1_bmp, NULL, NULL, NULL);
}

I didn't try upgrading my version because my friend managed to make it work, anyway, I can make the button show, but it is not responding to any of the mouse over/click...

PANEL* panel2 = pan_create("button_toggle(0, 0, red.bmp, green.bmp, blue.bmp, white.bmp, clickMe, leaveMe, overMe);", _VAR(999));

And the image of the button is always in green.bmp, which is the off state. The clickMe, leaveMe, overMe are just simple functions to do a cout message.

Do you see any mistake in that line?

Hi. I had same problem. Try this code:

char *sStart_pan; // this is a pointer to char array with code of panel
ev = engine_open(NULL);

if (!ev) return 1; // acknex.dll not found

//folder with button images
add_folder("%EXE_DIR%\\DATA\\Btn\\");

...
//Allocation of memory
sStart_pan = new char[strlen("bmap = Start_pan.jpg;\
button (381, 229, btnStart_d.jpg, btnStart_u.jpg, btnStart_u.jpg, meth1, NULL, NULL);\
flags = OVERLAY;")];

//copy code of panel to char array
strcpy(sStart_pan,"bmap = Start_pan.jpg;\
button (381, 229, btnStart_d.jpg, btnStart_u.jpg, btnStart_u.jpg, meth1, NULL, NULL);\
flags = OVERLAY;");

//create a new panel
Start_pan = pan_create(sStart_pan,1);

// make it visible
Start_pan->flags|=VISIBLE;

// wait some frame for visualisation of panel
for (int i=0; i<3; i++) engine_frame();

It's working on my computer.
The buttons is shown and method "meth1" is working.
I'm using MS Visual Studio 2005 and A7 engine (version 7.06.1)

With best regards.

And If you want to add Event on the button you should use
"pan_setevent" function

In my project (see example in previous post) i use this code:

pan_setevent(Start_pan,_VAR(3),_VAR(1),(EVENT)Change_Mode);
You can read more about this function in acknex help
