JavaScript无法执行'drawImage' [英] JavaScript Failed to execute 'drawImage'
问题描述
好的,所以我创建一个JavaScript Canvas Elements等游戏。我已经能够加载TONS的图片,但在一些选择,JavaScript回复与错误,如
Ok so I'm creating a game with JavaScript Canvas Elements and such. I've been able to load in TONS of Images, but on a select few, JavaScript replies with Errors such as
未捕获TypeError:失败在'CanvasRenderingContext2D'上执行'drawImage':没有找到匹配所提供的签名的函数。
Uncaught TypeError: Failed to execute 'drawImage' on 'CanvasRenderingContext2D': No function was found that matched the signature provided.
这使得NO SENSE,因为相同的代码在其他地方工作!?
Which makes NO SENSE at all, because the same code works in other places!?!
这是我的代码中的一个例子:
Here is an example I have in my code:
board.drawImage(document.getElementById("player_explode"), this.x, this.y);
在一个objects方法中, Player.die()
。
Inside of an objects method, Player.die()
, respectively.
有没有人知道为什么会出现这种行为?我非常沮丧...
Does anyone know why this behaviour is coming about? I'm getting very frustrated about it...
这里是 JSFiddle 来验证所有代码。
Player.die()
位于行[242]
。
推荐答案
问题是我加载图片的方式,我应该这样做:
The problem was the way that I was loading my Images, I should've been doing:
var image = new Image();
image.src = "imagesource.jpg";
但是我通过文档中的id获取元素
页面。
