I have an arraylist
ArrayList<int[]> strokeLines = new ArrayList<int[]>();
and a function which runs everytime the mouse is clicked which adds the current mouse position and the previous mouse position to this arraylist
strokeLines.add({mouseX, mouseY, pmouseX, pmouseY});
I had this code working earlier but I lost everything I wrote in the past hour, and when I rewrote this part it wouldn't work. How can I add the array {mouseX, mouseY, pmouseX, pmouseY} to the end of the arraylist?
您需要创建一个新的int[]
:
strokeLines.add(new int[]{mouseX, mouseY, pmouseX, pmouseY});
简单地-
strokeLines.add(new int[]{mouseX, mouseY, pmouseX, pmouseY});
