Saving click data to an table (Processing) - processing

Question

I´ve tried looking up the question but sadly I wasnt able to find my an answer to my question in other threads. :(
My problem is the following:
I´ve got my hands on a code which transfers clickdata into a heatmap.
Now what I would need is a way to transfer said clickdata into a table which documents the coordinates.
Here is the (hopefully) relevant part out of the code:
void mouseReleased()
{
if (mouseX >= 0 && mouseX < backgroundImage.width && mouseY >= 0 && mouseY < backgroundImage.height)
{
// blit the clickmapBrush onto the (offscreen) clickmap:
clickmap.blend(clickmapBrush, 0,0,clickmapBrush.width,clickmapBrush.height,mouseX-clickmapBrush.width/2,mouseY-clickmapBrush.height/2,clickmapBrush.width,clickmapBrush.height,BLEND);
// blit the clickmapBrush onto the background image in the upper left corner:
image(clickmapBrush, mouseX-clickmapBrush.width/2, mouseY-clickmapBrush.height/2);
// render the heatmapBrush into the gradientMap:
drawToGradient(mouseX, mouseY);
The code is used for the software "Processing".
I hope my question is specific enough.
Thanks in advance! =)

Answer 1

Here is a sample Processing sketch that will record a list of coordinates for each mouse click:
// We will store a list of coordinates,
// each representing a single mouse click's position
ArrayList<PVector> clickData;
void setup() {
clickData = new ArrayList<PVector>();
// Do any aditional setup you need here
}
void draw() {
// Do any drawing here
}
// Called after each press and release of the mouse
void mouseClicked() {
// Add the mouse's position to our list of mouse click positions
clickData.add(new PVector(mouseX, mouseY));
}
If you want to get the x value of the first recorded mouse click, for example, you can access it through a call to clickData.get(0).x, which first grabs the PVector at position 0 from clickData, then get's the x value associated with that PVector object.
Hope that helps!
