Press Button to run a auton section in driver?

[RNA]

Hello, My builder is getting on me about this but how could i code in driver control when a button is pressed, our arms and intakes lift the tray up without me doing it manually? yes its kind of dumb but our tray is a pain to deploy in driver and our auton deploy works 100%. Is there any way to do that?
Thanks,
Butters

A lot of Vex teams refer to it as “macros”. But the general idea is to take your auton deploy and encase it in a function. Then on the first button press, call that function.

ah. But how will i do it?

i have the else statement stop the motors.
Would i just do else if then if button pressed- run that section of the auton by Copying and pasting that section?
Im sorry if i am being stupid. I am not the best at coding and we have states in 2 weeks

I created an sample competition template below. In this example I created two functions because my team has two different paths that they want the robot follow depending on which side they are on. Then, in the autonomous() function I simply uncomment the program I want the robot to run.

Since I have each auton program in a function then I can call that function at anytime in my code. In the usercontrol I added code so that if a button is pressed then it runs that auton program.

//Sample comp code without comments.
#include "vex.h"
using namespace vex;
competition Competition;
controller Controller1;

void pre_auton(void) {
  vexcodeInit();
}

void autonBlue(void){
  //My team's autonomous code for the blue side.
}

void autonRed(void){
//My team's autonomous code for the red side.
}

void autonomous(void) {
  //We're going to be on the blue side for the next match.
  autonBlue();
  //autonRed();;
}

void usercontrol(void) {

  while (1) {
    //Include my standard controls to operate my robot

    //If I press ButtonUp then it will run autonBlue()
    if(Controller1.ButtonUp.pressing()){
        autonBlue();
    }
    wait(20, msec); // Sleep the task for a short amount of time to
  }
}

int main() {
  // Set up callbacks for autonomous and driver control periods.
  Competition.autonomous(autonomous);
  Competition.drivercontrol(usercontrol);
  pre_auton();

  while (true) {
    wait(100, msec);
  }
}

I know how to do it on blocks but you start off by doing when driver control>if(controller of choice) (button of choice) is pressed? then> ( commands you want so here you would put motor(x) spin 100 and like that) else> ( here you put to stop the motors.) I am yet to do this on my bot since i can only work on it at home but I can demonstrate my macro on which I use to move my intakes simultaneously.

so can i just use a section of code from my auton to driver? Like i have it stated in auton can i just say if button pressed. spin the motors to a certain rotation?

[SaltyCB]

literally like a regular button press then copy and paste. I would make sure it isnt required to hold down the button throughout.
So if button pressed then copy paste the auton deploy code and it will be fine

Best coding practice is to “not repeat your code” but yes you could just copy your code.

Better solution is to put your code in a function and then call that function from both places. That way if you change your program you only have to do it in one place.

[RNA]

Okay thank you all for your solutions. I will try to learn more about coding during the off season so i dont have to ask questions as much.

[AgocharB]

it would go something along the lines of…

void flipOut() {
     insert flip out code here
 }

void opControl() {
    while(true) {
    Controller.ButtonUp.pressed(flipOut);
    }
}

[RNA]

So i have to make a new void for the flip out code? and can i just do the controller thing in the driver control or will i need to put it in a new void

The term is “function” not “void”. The term “void” is a “type”, just like “int” or “double” are types. The “void” type just happens to not hold a value.

If you associate the function with a button “pressed” event, it will be called when you press the button. Do NOT put this registration inside a while loop, or every time thru the loop, a new association will be made and your function will not work as expected.

Unfortunately sometime it is not always as simple as this. If you have a function that lifts your arms to some predefined height and also have a button that you hold that raises them or lowers them (perhaps inside an “if button.pressing” condition), then you need to have a way for these two methods of telling the motor(s) what to do in a coordinated fashion.

[Mentor_355U]

Please do not put a call to register a pressed event inside of a loop. The example should be:

void flipOut() {
     // insert flip out code here
 }

void opControl() {
    Controller.ButtonUp.pressed(flipOut);
    while(true) {
       // Other user control here
    }
}

Can anyone spot the logical problem (I’m away from the programming environment, so this may not compile) in the code below (assume ArmMotor is a motor declared elsewhere):

void flipOut() {
       ArmMotor.setVelocity(50.0, percent);
       ArmMotor.spinToPosition(180, deg, true); 
}

void opControl() {
    Controller.ButtonUp.pressed(flipOut);
    while(true) {
     if(Controller.ButtonRight.pressing()) {
          ArmMotor.setVelocity(75.0, percent);
          ArmMotor.spin(fwd);
     } else if(Controller.ButtonLeft.pressing()) {
          ArmMotor.setVelocity(75.0, percent);
          ArmMotor.spin(rev);
     } else {
          ArmMotor.stop();
     }
     vex::task::sleep(50);
    }
}

UPDATE—
It works. thank you every one.
