I think we have a new kota here

First create the scenery with sea and fish.

You can add different fishes as AnimationFrame. (Set Animation speed to 0).

Pick a random Animationframe. (System expression random)

Then let the fish jump with bullet, physics, plattform, whatever you want.

Acutally the programmer decides whether a project becomes bogged down or not. Always try to use groups, function, comment your code etc. Never make anything twice.

You can store the inventory data in an e.g. array, Hashtable, dictonary etc.

You can use eventsheets in several layouts. Just add them.

How do you move the character in your former layout?

System-> Create Object

Make a new event sheet for the new layout.

On start of layout

spawn charactersprite

Put On pressed Button and overlapping door in one "And" Event.

No, there is no open door command

Imagine you have a house, this is your array. In your house there are rooms where you could store things. Rooms are in this case your X -Axis. Of course you could throw all your clothes on the floor of your room, but some of us decide to sort them. Thats why you need a wandrobe in your room. This is your Y-Axis. Now some kind of people (expecially women) are still not happy with just throwing all their clothes in the wandrobe. That's why they use drawers to seperate the underwear from the socks and so on. The drawers represent the Z-Axis.

House -> Array

Room -> X

Wandrobe -> Y

Drawers -> Z

I don't really understand what you're trying to do. But I can tell you what you're doing right now: You have a lot of underwear and to alocate them you write down in which room, which wandrobe and which drawer your underwear is right now. Afterwards you try to sort your underwear by the kind of drawer they're in. I think what you are really looking for is to sort them by the wandrobe they are in.

(it's also kinda strange that you say you have 6 rooms and with 6 wandrobes each but there's just a 5 * 6 matrix.

On pressed button

Character is overlapping door

Open door.

Can you show us what you already have? Cause normally an animation change doesnt affect movement.

Normally I don't use safari, but maybe this will help you: http://onvert.com/guides/enable-webgl-safari/
