Why you need to repeat 10 times? Since action will apply to all of the instances by default.

The Dungeon Tactics is an addictive one, great job! How much time you took to finish it?

You can use list control for dropdown menu, but it don't works on some platforms like cocoonjs.

I think the disabled events and actions is included in the exported code, as you can enable it back at the runtime.

Non- game apps are hardly created from any form of "drag and drop app creator", as most of the time it don't have any specific algorithms or features that suited to your project. Try to learn programming for yourself instead, it's not quite hard actually.

You can try the attached capx, click the button to toggle whether the button on or off.

Does the problem happened at your other projects?

If you're not doing any physics simulation or artificial intelligence, algebra, vector, basic geometry and trigonometry should be enough for most 2d games. You can learn more at here.

Aren't they already supported? Personally I think html5 export option is also viable in chrome os though.

If you'are using Platform behavior, simulate right button would done the right job easily. Other alternatives would be setting the vector x of your jet in positive value, or simply increases its x coordinates to move to right.

"On collide" condition just checks whether the collision polygons of two objects has "touched" each other, it don't handle the actual collision for you.

I've also experienced the same problem previously, and solved it after reading this post. Basically you just need to convert the pseudocode to C2 events.
