why is MIDI scripter dropping events after 20x loops in MainStage 3

my drum riff script seems to work up until the riff is repeated (i think around) 20 times. then some notes like snare... start to dissappear. if i hit the global stop and play again it works. also if i reload the script it doesn't help which makes me think... but come up with the road to nowhere. any ideas?
The problem starts at beat position 640 (20x 32 beats per loop).

The scripter plugin was loaded on a drum kit software instrument channel and works great for the most part.
I've traced each beat with another scripter plugin and all the notes have been logged, so i assume they've all been sent properly. All the notes should be there but they just can't be heard.
I've tried all kinds of things, i'm stuck!

How to wait for place ship click event to complete before calling next place ship function in JavaScript Battleship game loop

Problem: I call playerPlaceShip (from a DOM interaction module) inside a game loop module. This lets the user hover the board, click to place the ship, and finally in the event handler call board.placeShip() (from the gameBoard module). This works in isolation, but when I add another playerPlaceShip call to place an additional ship, it executes immediately before the first ship can be placed by clicking.
Desired outcome: A way to wait until the click event from the first function call completes before the next function call begins.
What I've tried: Hours of unsuccessfully trying to write and use promises. Hours of reading about promises. Spent a lot of time unsuccessfully trying to rethink how the code is structured. It seems like the click event should be driving the next action, but I don't see how to do that without writing more and more function calls inside the click event handler, which would seem to take control of the game flow away from the game loop module and put it in the DOM interaction module.
Full modules on GitHub: https://github.com/Pete-Fowler/battleship/tree/player-place-ships/src/modules
Code excerpts:
// In game loop module after creating ships, players, and board objects:
// Render Board
renderBoard(p1Board, p1Box);
renderBoard(p2Board, p2Box);
// Player place ships - lets user hover and click board to place
playerPlaceShip(p1Board, p1Carrier);
playerPlaceShip(p1Board, p1Battleship); // this gets called too soon before click event from the first call completes
// In DOM module:
const clickToPlace = (e, board, ship) => {
let { x, y } = e.target.dataset;
x = parseInt(x, 10);
y = parseInt(y, 10)
board.place(ship, x, y, axis);
renderShadow(e, 'place', ship.length);
removeListeners();
}
// Main function for player to place ship
const playerPlaceShip = (board, ship) => {
const squares = document.querySelectorAll('#p1 .board .square');
narrative.textContent = `Lead your ${ship.type} into battle. Press X to steer.`;
squares.forEach(square => {
square.addEventListener('mouseover', (e) => renderShadow(e, 'fill', ship.length));
square.addEventListener('mouseout', (e) => renderShadow(e, 'clear', ship.length));
square.addEventListener('click', (e) => clickToPlace(e, board, ship));
});
window.addEventListener('keydown', (e) => {
if(e.key === 'x') {
switchAxis();
squares.forEach(square => square.classList.remove('hovered'));
renderShadow(lastCoords, 'fill', ship.length);
}
});
}
Thanks!

I wasn't able to checkout the branch, got a strange error: invalid path 'src/images/background.jpg:Zone.Identifier', maybe because of the colon : after jpg. So I downloaded the zip.
Otherwise I would have done a pull request, that would be easier for you to merge.
I added logic so that the ship is always inside the board, and created a custom event to trigger after place ship. There are comments, see if this will help you move on.

Guessing game using random number. How to get new number without refreshing the page?

Im relativly new to js so im making a gueessing game from 1 to 100 using Math.random to get my random number. I have a play again button that clears all previous guesses from a previous round but when you click it the random number does not change so the next rounds number is the same
I tried stating random again in the play again function but it did not work and I also tried putting the variable in the function but then it changed upon every guess the user inputed
let random = Math.floor(Math.random() * 101)
console.log(random)
const guess = document.querySelector('.guess')
const button = document.querySelector('.submit')
const myForm = document.querySelector('.myForm')
let numguesses = 0
myForm.addEventListener('submit', click)
function click(e) {
e.preventDefault();
const ul = document.querySelector('.guesses')
if(guess.value > 100 || guess.value < 0 || isNaN(guess.value)) {
alert("please a enter number between 0 to 100")
} else {
numguesses++;
if(random != guess.value) {
if(guess.value > random) {
const eachguess = document.createElement('li')
eachguess.innerText= `${guess.value} was too High`
eachguess.classList.add('wrong')
ul.append(eachguess)
guess.value = '';
} else {
const eachguess = document.createElement('li')
eachguess.innerText = `${guess.value} was too Low`
eachguess.classList.add('low')
ul.append(eachguess)
guess.value = '';
}
} else {
const eachguess = document.createElement('li')
eachguess.innerText = `Well done you gueesed Correctly the number was ${random} it took ${numguesses} guesses`
eachguess.classList.add('correct')
ul.append(eachguess)
guess.value = ''
return
}
}
}
const PlayAgain = document.querySelector('#playAgain')
PlayAgain.addEventListener('click', Play)
function Play() {
const ul = document.querySelector('.guesses')
while (ul.firstChild) {
ul.removeChild(ul.firstChild)
numguesses = 0
}
}

You can assign a new value within the Play function:
let random;
// ...
function Play() {
const ul = document.querySelector('.guesses')
while (ul.firstChild) {
ul.removeChild(ul.firstChild)
}
numguesses = 0
random = Math.floor(Math.random() * 101) // <------
console.log(random)
}
You must not add the let keyword here as that would declare the random variable locally within the Play function - but in your case you want to re-assign the existing variable from the outer scope).

THREE.js - Updating BufferGeometry position twice, causes my FPS to suffer

I have an array of TubeBufferGeometrys that im making animate to look as if they're growing out in length. When the animation runs the first time, it works really smoothly at 60fps. But once i set the geometrys position attributes back to zero, the FPS drop to 30.
Ive isolated my animation to run and then rerun once it finished with only the below changing. Heres the basics of my code:
Animation control view
stop() {
this.play = false;
// Start it again
setTimeout(() => {
let i = this.tubeCount;
while (i--) {
this.tubes[i].lastSegmentSet = 0;
this.tubes[i].updateToPercent(0);
}
this.elapsedTime = 0;
this.startTime = Date.now();
this.play = true;
}, 2000)
}
update() {
requestAnimationFrame(this.animate);
// ..render stuff + composer that ive disabled without effect
if (this.play) {
let percent = (Date.now() - this.startTime) / ANIMATE_DURATION;
if (percent >= 1) {
this.stop();
}
let i = this.lineCount;
while (i--) {
this.tubes[i].updateToPercent(percent);
}
}
}
Tube class (The main animation code)
constructor() {
//..other stuff
this.lastSegmentSet = 0;
}
// I first build the paths, then store the position data to use later to animate to. Then i set all the position data to zero
storeVerticies() {
this.positions = this.tube.geometry.attributes.position.array.slice(0);
const length = this.tube.geometry.attributes.position.array.length;
this.tube.geometry.attributes.position.array = new Float32Array(length);
}
setSegment(segment) {
this.setSegmentTo(segment, segment);
}
setSegmentTo(segment, target) {
let position = this.tube.geometry.attributes.position.array;
let startPoint = segment * JOINT_DATA_LENGTH; //JOINT_DATA_LENGTH is the number of values in the buffer geometry to update a segment
let targetPoint = target * JOINT_DATA_LENGTH;
let n = JOINT_DATA_LENGTH;
while (n--) {
position[startPoint + n] = this.positions[targetPoint + n];
}
}
updateToPercent(percent) {
let endSegment = Math.floor(percent * this.segmentCount);
while (this.lastSegmentSet <= endSegment) {
this.setSegment(this.lastSegmentSet++);
}
let n = this.lastSegmentSet;
while (n <= this.segmentCount + 1) {
this.setSegmentTo(n++, this.lastSegmentSet);
}
this.tube.geometry.attributes.position.needsUpdate = true;
}
Will put bounty when possible

Javascript for loop doesn't work (adding numbers to a total)

I am using Jasmine for JS testing, and unfortunately I can't get the following test to pass.
it('should know the total game score', function() {
frame1 = new Frame;
frame2 = new Frame;
game = new Game;
frame1.score(3, 4);
frame2.score(5, 5);
expect(game.totalScore()).toEqual(17)
});
The error message I get is as follows: Error: Expected 0 to equal 17.
The code is as follows:
function Game() {
this.scorecard = []
};
Game.prototype.add = function(frame) {
this.scorecard.push(frame)
};
// Why is this not working!!???
Game.prototype.totalScore = function() {
total = 0;
for(i = 0; i < this.scorecard.length; i++)
{
total +=this.scorecard[i].rollOne + this.scorecard[i].rollTwo;
}
return total;
};
function Frame() {};
Frame.prototype.score = function(first_roll, second_roll) {
this.rollOne = first_roll;
this.rollTwo = second_roll;
return this
};
Frame.prototype.isStrike = function() {
return (this.rollOne === 10);
};
Frame.prototype.isSpare = function() {
return (this.rollOne + this.rollTwo === 10) && (this.rollOne !== 10)
};
Adding the numbers together manually seems to work e.g. total = game.scorecard[0].rollOne + this.scorecard[0].rollTwo , but the for loop (even though it looks correct) doesn't seem to work. Any help would be greatly appreciated :)

I am not pretty sure, but it seems that you are not calling the "Add" method, so no data is added to the scorecard.

You have to add the Frames to your game i guess
it('should know the total game score', function () {
frame1 = new Frame;
frame2 = new Frame;
game = new Game;
// those lines are missing
game.add(frame1);
game.add(frame2);
frame1.score(3, 4);
frame2.score(5, 5);
expect(17).toEqual(game.totalScore())
});
otherwise, the scorecard-array is empty and the total score is therefore equal to 0.

missing (so no data is added to the scorecard.)
game.Add(frame1);
game.Add(frame2);
