I want to have a variable where i can put in a percentage of the calculation. so i can adjust it by changing the variable.

only the calculations that processing does are not correct. its probably the way i typed it but i cant figure it out.

here is my code:

2. int a = 2;
3. int b = 2;
4. int percentage = 75;
5. float total = a * b/ 100 * percentage;
6. 
   
7. println(total);

the solution has to be 3. but it returns 0. i cant use it in my program like this because its inaccurate.

maybe you guys know how I have to type it that it works.

Thanks in advance

i got one small question. i want a timer to start and count in my program after a start it. i got an opening screen and if i press enter it goes to the main screen and i want the timer to start then instead of the beginning of the program. i made an small example of what is in my code. maybe you guys can help me.

here is my code:

2. int begintime = 5;
3. int window = 0;
4. 
   
5. void setup() {
6.   size(400, 400);
7.   background(0);
8. }
9. 
   
10. void draw() {
11.   if (window == 0) {
12.     background(#FF0000);
13.   }
14.   if(window == 1) {
15.     background(#FFFFFF);
16.     int sec = frameCount/60;
17.     int timer = begintime - sec;
18. 
    
19.     if (timer <= 0) {
20.       window = 2;
21.     }
22.   }
23. 
    
24.   if(window == 2){
25.    background(0);
26.   }
27. }
28. 
    
29.   void keyPressed() {
30.     if (keyCode == ENTER) {
31.       window =1;
32.     }
33.   }

Thanks in advance

I dont like to use a timer based on framerate or delay because it slows the program,

and i used millis() now but that starts from the beginning of the program. is there another way to make a timer or

is there a way to make milllis() start on command?

 

Thanks in advance.

if i try to run the program i get this error.

what am i doing wrong.

i got a problem. i need a game sort of qual to snake. and i have my triangle and moving. but i use that in the draw.

so i need the balls to be in the void draw too. but if i give them a random they keep moving. if i declare it globally outside the voids. it starts with one position and thats good. but i want to go over the ball with the triangle and then it needs to dissappear and appear somewhere random on the screen. and let that dissappear again if I go over it with the triangle.

it also needs to fit in little squares of 40. so the triangle fits perfectly over the balls.

I already tried something but that didnt work out.

hope you guys can help me out.

I got the following problem. I have a void drawTriangle() and a void drawCircles().

I use void drawTriangle in the void draw so I can move it. in drawTriangle I use background(0);

so the background is black. now i want void drawCircles to draw random circles one time.

but if i put it in de void Setup() it only draws the circles randomly and the void draw overwrites it with a black background.

if I put drawCircles in the void Draw it keeps drawing Circles randomly and the circles jump around the screen.

is there a way to draw them once in the beginning and keep them on the screen.

Hope to hear from you soon.

I got a moving Triangle in my program and i also have a few screens you have to go trough by pressing enter.

Now i only want the triangle to be controllable in the last screen. but for it to move it needs to be checked constantly and that is where void draw is for. but if i put it in draw it wont show the other screens. is there a way to do it without draw?

Thanks

I wonder if i could hide the Control.p5 numberboxes? i can get them in a program but i want them to leave after a certain

time and i haven't figured out yet how to do it.

Hope that you can help me.

I'm pretty new to Processing and for my program that I am making I want to move a triangle with the directional arrows on the keyboard.I found a way to do it but the code is very long and it gots bugs because the triangle gets really weird shapes when i keep moving. 

This is my code for the moving triangle:

I hope that you guys can help me because i really want to finish this program.

Thank you very much!
