simulate a fall

Hello,
i've a problem with a simulation of a fall. I created a rect that you can drad & drop on the screen. I would like it to be falling vertically when you release it. I tryied with this piece of code:
Quote:
// mex= x coordinate / mey= y coordinate of the rect
if (release) {
mex = mouseX;
mey = 50;
} |
|
It is falling right but you can still move the rect horizontally after... I couldn't find a way to recover the value of mouseX when the mouse is released, and to assign it to mex.
I also tried to make it with booleans but it didn't work well :/
If someone could explain me how to solve it?
Thx a lot.

i think you are doing this a little too complicated, but anyway here's how to solve your problem:
Code:if (release) {
//mex = mouseX;
mey = 50;
dragdrop = false;
} |
|
if you assign mouseX here it will keep following the mouse .. and dragdrop has to be set to false (somewhere) to recover from dragging.
Code:void mouseDragged()
{
// if mouseDragged on the avatar
if ( mouseX > mex && mouseX < mex+32 && mouseY > mey && mouseY < mey+73) {
dragdrop = true;
release = false;
}
} |
|
( no need to check for mousePressed in mouseDragged .. that for sure in there ... )
set release false here, otherwise it will release the drag-drop in the loop ...
-----
less is more and might not get you confused with all that bools ..
Code:
void me () {
blockx = constrain(mouseX-16, 0, width-32);
blocky = constrain(mouseY, 0, 50);
fill (120, 30, 10);
rect(mex, mey, 32, 73);
if ( dragdrop ) {
int blockxint = int(blockx);
int blockyint = int(blocky);
mex = blockxint;
mey = blockyint;
if (mouseX < 15 && mouseX >-100 || mouseX > 200 - 32 && mouseX < 300 || mouseY <3 && mouseY>-100 ) {
fill (0);
rect (100, 100, 10, 10);
}
} else {
mey = 50;
}
}
void mouseDragged()
{
if (mouseX > mex & mouseX < mex+32 & mouseY > mey & mouseY < mey+73 ) {
dragdrop = true;
}
}
void mouseReleased()
{
dragdrop = false;
}

You're right for the bools, i made too many this was useless... I'm stupid, the solution was so easy :s
By the way, thx fjen, i learned a lot with your code !
