Calling different draw functions

Processing Coding Questions

Update: I can make the void draw() call the drawTree() function, but it doesn’t actually draw anything on the screen. I am trying to just draw some lines at first. drawTree looks like this:

void drawTree(){
println(“drawTree”);
for(int i = 0; i < 50000; i++){
line(50,50,200,200,i,i+100);
}
}
I am using P3D so I figure I need to give 3D coordinates. Anyone know what I am doing wrong?
