I'm currently working on a simple JavaScript game that involves a falling random object (trash) and another object used to catch the falling trash (trash bin). While everything seems to be working fine, I would like to improve the smoothness of the movement of the trash bin. Do you have any suggestions on how to achieve this? Thank you in advance.
Here is a snippet of my code:
// Your code goes here
}
One important aspect to consider is using only one instance of requestAnimationFrame and avoiding multiple uses of setTimeout. When these functions begin to run out of sync, it becomes difficult to pause the game smoothly when needed.
Instead of relying on timeouts, utilize a counter in your code.
let fruitCounter = 0
function drawGame() {
// include all drawing logic here
...
// drop a new fruit every 60 frames
fruitCounter++
if(fruitCounter > 60){
fruitCounter = 0
dropNewFruit()
}
// continue requesting frames unless the game is over
if(!gameOver) {
requestAnimationFrame(drawGame)
}
}
Moreover, keyboard events can result in choppy gameplay due to input delays. To address this issue, set a variable upon key press.
window.addEventListener("keydown", function(e){
if(e.keyCode == 37){
moveLeft = 1
}
}
window.addEventListener("keyup", function(e){
if(e.keyCode == 37){
moveLeft = 0
}
}
You can then incorporate this variable into your animation logic.
function drawGame() {
// include all drawing logic here
player.x += moveLeft
// continue requesting frames unless the game is over
if(!gameOver) {
requestAnimationFrame(drawGame)
}
}
These are just a few helpful guidelines that have proven effective in my experience developing JavaScript games.
