I am a beginner and working through the book with class (we are on chap 5). My problems are: 1. I can't get the houses to recognize image2 (trunk up) of Firefighting elephant, so have settled for having the fires put out with main image (trunk down). 2. I have stuck delays into my on fire animation because it goes so quickly as to be unrecognizable otherwise, but this slows down all of the characters. 3. For game loss, I wanted to set up a counter of image 1 houses (not burnt) and if it got to < 3, (only two houses unburnt currently), Greenfoot.stop., but I don't know which method counts specific objects or where I would place it (in my World?). 4. I want to attach a guttering flame animation to the tip of the match as a separate object that would travel with the match and stay in its proper place (at end of match), so that when elephant controller goes to blow out match, blowing out the non-fire end of match would not work--player would have to aim at the flame. Maybe this is too complicated and I should just leave the match as all one piece, but can it be done? (have two objects travel randomly together?) 5. In general, I am wondering where I can put code that involves the interaction of specific images (not the original "setImage=image1", but some later image) from more than one class. Can we write act into World?
