I am trying to make a game using processing where a cube follows a set path and has to jump over obstacles.

in Programming Questions • 2 years ago

So far this is what i have, i just need to find a way to get my object back down after it jumps

float boxy;

void setup()

{

size(400, 400);

boxy = height - 50;

}

void draw()

{

background(120);

if (jumping) {

boxy--;

}

rect(width/2, boxy, 20, 20);

}

boolean jumping = false;

void keyPressed()

{

if (keyCode == 38 && !jumping) {

jumping = true;

}

Hi, so far, you are saying:

--box starts at (height-50)

--if the key is pressed, jumping is true

--if jumping, raise the box (boxy--)

So you need to add a way to set jumping to false:

--if the key is released, jumping is false

--if jumping is false (!jumping), drop the box (boxy++)

(could just be an 'else' statement after the jumping check)

If you want the box to stop falling when it hits a "floor level," try using:

boxy = min(floorLevel, boxy++);

One other thing -- not everyone has a key code '38'. I couldn't find one. You can also code by the character the key produces, which is a more portable method:

if (key==' ') // do something with the spacebar

[Edit -- oh, up arrow. Yeah, not everyone has those.]
