Read up on 'intersect' in the dictionary...

Monsieur problème knows about "intersect": http://forums.livecode.com/viewtopic.php?f=7&t=26008

But obviously not much about meaningful thread titles!

Hi.

Do you mean that you do not know in advance which branch the bird will land on?

If so, you still need to test for "intersect", but you also need to test for each branch: (pseudo)

Code: Select all

move bird down
get the number of images
repeat for each image tImage in it
if intersect(bird,tImage)...
