Why does my screen change when an Image Sprite hits another Sprite

Hi! I was wondering if you could help me with a bug I am having. For some reason when one of my sprites collide with another sprite then it changes screen when I don't want it to. Here is the AiA file:

EscapeRoom.aia (433.4 KB)

You are totally misusing the collision event blocks.

See http://www.appinventor.org/bookChapters/chapter17.pdf

from the free book at

Yes I think I finally got it figured out now thank you so much!!

Here is my new .aia file:

EscapeRoom (1).aia (433.9 KB)

Now fix your other level.

It also wouldn't hurt to do some testing.

If you are planning on a lot of levels, learn how to reuse a screen and load levels from files.

Now that problem is fixed but another one came up. Now on level 2 when one cop hits the edge the other cop changes direction. Here is a third file:

Uploading: EscapeRoom (2).aia(1)...Processing: EscapeRoom (2).aia...

Thank you so much for teaching me how to do that! Such a time saver!

What is the latest problem?

Please download and post each of those event block(s)/procedures here ...
P.S. These blocks can be dragged directly into your Blocks Editor workspace.

See Download Block Images for a demo.
