Things like blob opera6/3/2023 As you can see this will go on forever unless I do something to stop it, but that’s another story. The second is the waiting time in milliseconds, meaning setTimeout will wait 30 milliseconds before calling mainLoop again. Here the first parameter is the function I want to run, namely mainLoop again. When all this is done I call the setTimeout function. For example:įirst I call mainLoop, which in turn will call drawSomething - this draws the current state on the canvas, while updateAnimation calculates our object’s new position and move it. ![]() The easiest way to do this is to set up a time-out function in JavaScript. You will probably want to animate things before long as well. It’s all really simple and Blob Sallad as such doesn’t use anything outside the standard API (see for further coverage of the API.) Animation basics When you are done with your path you call stroke and voila. When you want to start drawing you call use beginPath and move the cursor around using moveTo and lineTo. The context is the actual drawing area and as you can see we manipulate different properties of the context such as line width and stroke color. The second line probes the canvas for its context. ![]() The first two lines in the drawSomething function will find the canvas object using getElementById, just like with any other HTML object. Var canvas = document.getElementById('blobs')
