Help with making mouse rollover work

in Programming Questions • 8 months ago

I have been struggling with this code for weeks now. Please take the time to go through my code and tell me how I can make the function display the tweet when the mouse hovers over it. So far, I have only gotten it to display only the last tweet. I think this is because the x and y values a plotted randomly and keep changing with each pass. I will want to be able to hover over all the plotted shapes and display their respective tweets. I have received help from some people in this forum, about cleaning up the code and making it better, but the fundamental issue remains unresolved. I'm running out of time! Thanks in advance.

you need to post your entire code, also class User and class GeoLocation and TwitterStream....

This is the entire code. The only thing I left out was the twitter4j import functions and my access keys.

class Ball? Better name?

but class GeoLocation is still missing? Or is it part of twitter4j ?

In general during debugging I wouldn't use try since it can obscure error messages

Then I read this code:

raw() {
myBall = new Ball(random(width), random(height - 200));
myBall.run();
}

Since .run() is calling function tweet() where your mouse over takes place you want to have your mouseover on the ball.

But you get a new ball 60 times per second, every time with a new position.
You can therefore not hit it with the mouse.

Better have line 3 in setup() and not in draw().

I can't run your code because I don't have the lib or an access key.

Another source of error could be wrd and wrd2 - they could hinder the mouse over message. Maybe set them to true for testing and finding the error.

Greetings, Chrisir
