Scratch

Here you go.


1. This depends greatly on what you're doing. If there's a solid wall that's straight up and down, set the control sprite so if its X or Y position is at the wall, make the X or Y position move. Or if the walls are unpredictable (in other words, if they are in weird positions and things), try making the sprite switch direction by 180 and moving some steps. With the [point in direction [((direction) + 180)]] blocks and the [move [ ] steps] block, of course. You could change the + to a - if you want to; it won't make any difference.

2A. If the spikes are a certain color that nothing else is, you could use the <touching color [ ]> block for when the control sprite dies. If there are other things that are the same color as the spikes, you could make the spikes sprites and use the <touching [Sprite 1]> block instead. Of course, if it's only things that kill you that are a certain color, then it doesn't matter about if there's something else that's the same color. They all kill you; use the <touching color [ ]>.

2B. For the control sprite to go back to the beginning of the level, there are two things:
   1. If it's a scroller, just set the Scroll X (or Scroll Y if you're using it) to the right spot.
   2. If it's a 'go through background' level, just set the background and the X and Y for the sprite.

3. If the goal is a certain sprite, use the <touching [Sprite 1]> block to broadcast the next level. If the goal is something in a sprite or background, try using the <touching color [ ]> block. Of course, this won't work if there's something else the same color. If this happens, try using a sprite as the goal; it'll make it much easier. See the beginning of this section.

4. Make a sprite that'll act as the 1-up, and use the <touching [Sprite 1]> block for detecting if the control sprite is touching the 1-up. When it touches, hide the 1-up and broadcast a life change (like changing the health variable or custom display by 1).

5. Tell me about them.


Hope this helps!

For the 1up here is a script

<when green flag clicked>
<forever if><touching[ 1up
<change{ lives }by( 1
<wait until><<  <not> <touching[1up  >>
<broadcast[ hide 1up
<end>

Keyboard not found, press any key to continue.

Well, how do I make life count?

Display the variable "life"

You want help from an experienced Scratcher, and although I've been Scratching for a couple of years I'm still in the early stages.  But there is one thing that I would suggest from reading your post and the replies: take things one at a time.  Trying to build a whole game with all the things you want is quite a job....as you say.  My humble advice would be, for now, to build a project where something hits a wall and bounces off.  That's it. Then maybe add the fact that if it *hits* the wall it scores a point.  And then, if it scores 5 points it moves up a level (using the tips that people have given you).  For keeping track of the score you would probably use a variable "Score".....and that's a whole subject in itself: variables.  You could make some fun projects where bouncing off of blue walls adds a point, but bouncing off of gray walls loses a point.  ------- In short, you'll probably feel less frustrated if you break big projects down into manageable pieces.  That's my humble opinion.... 

How do you make stuff appear in the loading screen!!!!!!!!!!!!!!!!!!!!!!1<mouse x><mouse y><mouse down?>
