[英]How to enable right click in p5.js?
I'm making a minesweeper clone, left click reveals the cell and right click is supposed to flag the cell.我正在制作扫雷艇克隆,左键单击显示单元格,右键单击应该标记单元格。
I'm using the function mouseClicked()
- this allows me to reveal on left click and also reveal on right click.我正在使用功能
mouseClicked()
- 这允许我在左键单击时显示并在右键单击时显示。
I tried using我尝试使用
if(mouseIsPressed) {
if(mouseButton === LEFT) {
reveal
}
if(mouseButton === RIGHT) {
flag
}
}
This registers once every frame that the button is held down.这将在按下按钮的每一帧中注册一次。 I just want a single right click.
我只想单击右键。 I imagine there is something simple that I'm missing, but I really can't find anything in the documentation or anyone asking about it online.
我想我遗漏了一些简单的东西,但我真的在文档中找不到任何东西,也没有任何人在线询问它。
TL;DR - I just want to be able to right click in p5.js. TL; DR - 我只想能够在 p5.js 中右键单击。
The mouseClicked()
event only occurs once when the mouse button is pressed. mouseClicked()
事件仅在按下鼠标按钮时发生一次。
Set a state flag when the event occurs:事件发生时设置状态标志:
var rightPressed = false;
function mouseClicked() {
if(mouseButton === RIGHT) {
rightPressed = true;
}
}
Reset the flag when the action which is triggered by the event was handled:处理事件触发的操作时重置标志:
function draw() {
if (rightPressed) {
rightPressed = false
// do somthing
// ...
}
}
Use the mouseClicked()
function and pass the event
.使用
mouseClicked()
函数并传递event
。
Then using event.button
you can determine if it is a right click like so:然后使用
event.button
您可以确定它是否是右键单击,如下所示:
function mouseClicked(event){
if(event.button === 2){
// Right click
}
}
