Forums » Impact Engine » iOSImpact and ig.system.context issue.

I'm using iOSImpact, which is working great.

Except for when I use the following code inside my main.js:

// Calculate health remaining.
ig.system.context.fillStyle = "rgb(105, 3, 7)";
ig.system.context.beginPath();

ig.system.context.rect(meterX, 52, healthMeter, meterHeight);
ig.system.context.closePath();
ig.system.context.fill();

I get the following error(s)

TypeError: 'undefined' is not a function (evaluating 'ig.system.context.beginPath()') at line 324 in lib/game/main.js

Any help would be greatly appreciated as this is an important bit of functionality for my game.

Also if I wanted to only include the following plugin when ig.ua.mobile is true how would I go about that considering it sits inside the requires() block of main.js?

I only want this to be included for mobile:

'plugins.ios.ios'

Thanks in advance.

I don't think iOSImpact supports paths at all.

Arantor is correct. The current implementation of iOSImpact does not support paths.

According to Dominic however, the next version should.

In the meantime, you could use Ludei's CacoonJS, however I find it to not be as performance as iOSImpact.

@alexandre: I tried CocoonJS, got everything working (apart from my player animations looking absolutely ridiculous). Then I learned that there's actually no touch events with Impact yet and gave up.

Um, Impact maps the touch events to the mouse, as the input area describes. It doesn't do multi-touch or gestures, however there is a plugin (including for iOSImpact) for multi-touch.
