Tap few times working / few times not + instance string comparsion

Hi! Yesterday I bought C3 licence to do some tests and maybe to start work with.

...Aaaaaand logic of work in Construct 2 here is unacceptable or I have encountered some bugs (don't realy think so due to lack of experience)

First problem is that "compare instance variable" doesn't work with tap-object event, even as sub-event. In a new clean project with few images. But I don't understand why? Because it working in the same C2 project (((

Second problem occured while I was trying to make another project just to show first one on simplified example. And when I'm trying to tap on sprites tap event fires sometimes and sometimes not.

I've tested this on pc, notebook, and phone. Even compiled it doesn't work.

How can this be that it's only second day with C3 and it doenst work as expected? How many other surprises I will face? And why all of this was working on C2 like a charm?

Thank you in advance! I really need some help, please)

Already found one answer:

After setting value to string instance variable you need to delete quotes in C3 editor. They defaultly appear and there is firing compare event with string in «double-quotes»

Yes that's right for the first problem. For the second problem look at your collision boxes on the sprite.

Okay, strings must be with quotes in some places and without quotes in other, that is summary.

How about tap-freezes in example with 4 unnamed buttons? Any thoughts?

P.S. I can't find «edit» button on topic, where it is?

Yes that's right for the first problem. For the second problem look at your collision boxes on the sprite.

Set to bounding box resolved this! Thank you very much! I was thinking collision polygon doesn't apply on tap event, after other engines this looks strange to me)
