royibernthal Posted June 27, 2017 Share Posted June 27, 2017 I have an Ionic app that uses the latest versions of angular 4 and ionic 3. I'm using PIXI (4.5.2) in one of the screens in it - the game screen. The player frequently moves in and out of that screen. Before starting the game I'm: -Preparing resources -Moving to game screen -Adding the canvas (app.view) to DOM Before moving away from the game screen I'm: -Destroying resources and resetting the PIXI.loader -Removing the canvas (app.view) from DOM Most of the time everything works fine, but rarely when I'm moving away from the game screen I'm getting the following error: Quote Runtime Error Cannot read property 'width' of null Stack TypeError: Cannot read property 'width' of null at Image.e.calculateVertices (http://localhost:8100/assets/imageSwapper/pixi.min.js:14:13368) at Image.e._renderWebGL (http://localhost:8100/assets/imageSwapper/pixi.min.js:14:14230) at Image.e.renderWebGL (http://localhost:8100/assets/imageSwapper/pixi.min.js:10:21822) at Swapper.e.renderWebGL (http://localhost:8100/assets/imageSwapper/pixi.min.js:10:21898) at e.renderWebGL (http://localhost:8100/assets/imageSwapper/pixi.min.js:10:21898) at e.render (http://localhost:8100/assets/imageSwapper/pixi.min.js:13:8590) at t.render (http://localhost:8100/assets/imageSwapper/pixi.min.js:10:10909) at t.emit (http://localhost:8100/assets/imageSwapper/pixi.min.js:16:7855) at t.update (http://localhost:8100/assets/imageSwapper/pixi.min.js:16:6834) at _tick (http://localhost:8100/assets/imageSwapper/pixi.min.js:16:5017) at t.invokeTask (http://localhost:8100/build/polyfills.js:3:12256) at Object.onInvokeTask (http://localhost:8100/build/main.js:4539:37) at t.invokeTask (http://localhost:8100/build/polyfills.js:3:12177) at n.runTask (http://localhost:8100/build/polyfills.js:3:7153) at invoke (http://localhost:8100/build/polyfills.js:3:13213) I don't know yet why this error only rarely occurs and why.
