Mouse-Over a Bitmap...
Author
Hey People.
It''s me...again hehe.
In Allegro i''m trying to make a mouse-over work on a Bitmap, the mouse-over is working fine using this code..
wouldn't you just do the exact opposite?
like:
mouse_x > 230 && mouse_X < test.x
etc.
then change the pic back to the original
-btw, how do you make a code box like that? i'm new

Welcome to the wonderful world of "Programming is not easy".
Have a variable like;
int ButtonState;
Then it can have values;
#define HIGHLIGHT 0
#define UP 1
#define DOWN 2
Then you can have a statement like
if(mouse over the button) ButtonState = HIGHLIGHT
if(mouse over button and clicked) ButtonState = DOWN
else ButtonState = UP
And THEN draw the button -- You could even have the buttonstate be an index into a BITMAP array so you could do something like
blit(screen, button[ButtonState],.....);

Using an else statement in which you set the bitmap back to the original should work. For example,
if (mouse_x==whatever && mouse_y==whatever)
{
//change current bitmap
}
else
{
//mouse is not over the bitmap, so change it back
}

Couldn't you just do and else?
EDIT:
I just noticed this.
Shouldn't:
if (mouse_x < 230 && mouse_x > test.x && mouse_y < 190 && mouse_y > test.x && hover == 0)
Be:
if (mouse_x < 230 && mouse_x > test.x && mouse_y < 190 && mouse_y > test.y && hover == 0)
The test.x should be test.y?

Else Statement didnt work, but i''m going to try nonnus29''s idea in the morning, i''m off to bed, Thanks for your help.

Dean.
If else doesn''t work, then you have an error in your routine to check whether the mouse is over the bitmap, because the else part is executed when the if statement is false.
Did you fix the error UltimaX has stated??
should work to tell if the mouse cursor is outside the bitmap.

if ((mouse_x > 230 || mouse_x < test.x) && (mouse_y > 190 || mouse_y < test.y) && hover == 1)should work to tell if the mouse cursor is outside the bitmap.
