collision detection using keys

Rossid992

i am making a game where you have to catch items as they fall, i managed to get the collision detection to work with the mouse function, but as i am making it to work with arduino i cant get the collision detection to work, code is below, thank you for any help.

where's your mouse collision detection? Which lines?

What have you tried? in which lines?

Since you have only one ball, I assume you want to catch with the ball either an egg or a cherry etc.; is that correct? You don't say.

Anyway, for collision detection you have to loop over all cherrys, eggs and so on and test against ball position:

//if icecream be catched
if (x-30<ball.x && ball.x+ball.r < x+30 && 
    y_icecream[i]-30<ball.y && ball.y+ball.r<y_icecream[i]+30) {
        score= score+2;//score +2

Remark:

Later you want to have an item class for all egg and icecream etc... since at the moment, the x-pos is always the same for them...

The item class would look like the ball class just with an PImage in it.

You can have an ArrayList of that class then.

;-)

Rossid992

thank you for your help really appreciate it :) however i am no getting an error saying:

ball.x cannot be resolved or is not a field.

Chrisir

ball1.x

PhiLho

You have both a ball class and a ball variable (which is not an instance of the class!). You should stick to the convention of naming classes with an initial uppercase letter: class Ball, variable ball, etc.

Rossid992

so i have done as suggested and i am getting an error the function display() does not exist. sorry to be a pain i am still learning.

Chrisir

do you have ball1.display();

?

Pls show your code

Chrisir

remark 1

• you got one class ball (which you should name Ball or BallClass)

• you got one image ball (which you should name ballImage or so)

• you got one object ball1 (which name is ok, you could say ballObject)

remark 2

• you got one display() outside the function that you never use; delete it. Because you have one display in the class that you use.

pls note, you can't say ball.display, because ball is the name of the class (or the image); you must use ball1.display() since ball1 (with 1) is your object.

there is a tutorial on OOP (classes & objects) - pls read

we can't run your code since we don't have the images and the arduino with the buttons

this is your stripped down code - keys 4 and 5

i am still having no luck with it :| i have tried everything suggested above and get new errors is there any way of posting the actual file to show?

Chrisir

post your code here or in dropbox (public)

maybe ask in the arduino forum http://arduino.cc/en

Rossid992

https://www.dropbox.com/s/27m0gixd8f5wa43/sketch_150102990oop2.zip?dl=0 i have changed it so you don't need the arduino as suggested. :)

Chrisir

hmm...

the thing is, your images are much bigger than they seem to be...

they have a kind of transparent background around them

so their x,y position is in fact far left and above each image.

I countered that by saying ´imageMode(CENTER);´ which makes it so that x,y is in the middle / center of each image.

You can also cut the frame that is around each image in a separate graphics program like irfanview.

it works now for the eggs. I had to take out ´time = 0;´ though; that froze everything.

instead of the collision approach with > and && etc. you might want to try rectangle collision (but actually I think the former approach is good enough).

Best, Chrisir ;-)
