Scratch

Meh thinks those blocks should exist but a drawing Stage...?!?!?!?!?!

yes they would be avaliable to sprites and stage. I just thought of another one:
|make dot at x: () y: () size ()|

I mean not like the stage moving around, that would be confusing (although useful!!!) but what I was thinking was some blocks in the pen catogry that the stage can also use that let you draw lines, rectangles, circles and floodfill stuff. Then the stage could also have a pen colour. The blocks would be:

Code:

|draw line from x:() y:() to x:() y:()|
|draw rectange from x:() y:() to x:() y:()|
|draw circle with centre x:() y:() and radius ()|
|draw circle with centre x:() y:() and circumference ()|
|floodfill at x:() y:()|

All of those can be done with sprites, but floodfill takes time to do, and you have to be good at Scratch.

What would you do with these blocks that you could’t do with Scratch now?

Well,  there are 5 payoffs to using thees blocks then there is to puting them in a sprite:
1: They will save time (perticually floodfill) both to run and to make, and won't require you to make extra variables to remember the position.
2: They won't change the pen state. This is useful because making a drawline broadcast  script would have to put the pen down, and then bake up at the end. This assumes the pen is up to start with, and if it didn't put the pen up at the end, it assumes it was down in the first place. There is no < pen down> boolean so we have no workaround. But theese functions wouldn't assume anything so that is good.
3: They won't make the sprite flash. You could use a sprite that is just a dot to avoid that, but what if it was a 1s1s project?
4: A sprite could run more than 1 at a time. This is important because otherwise the variables you made to remember x and y positions would change otherwise.
5: (the whole point of this post) THE STAGE CAN USE THEM!!!!!!!!!!!!
Tell me if you think of any more payoffs.

Using my squeak knowledge, technically, the stage should be able to move. You see, EVERYTHING in Squeak is an object, so in Scratch, the blocks, sprites, variables and buttons are objects.

Anyway, support!

Draw shape [circle v]

block aswell? I'm afraid that the circle blocks you have listed might confuse new scratchers. but it would also have a dropdown menu to choose a shape.

You can simply use a script like this:

when gf clicked
repeat (360)
stamp
move (steps) steps
turn (1) degrees

when gf clicked
repeat (number of sides)
stamp
move (steps) steps
turn (((180)*((number of sides)-(2)))/(number of sides)) degrees

Half-support...

And for regular polygons:

when gf clicked
repeat (number of sides)
stamp
move (steps) steps
turn (((180)*((number of sides)-(2)))/(number of sides)) degrees

The order of the blocks can be wrong, so don't quote me on the order.

But you can't move the stage... only sprites can do that.

Will someone realize that this is for the stage?

Yes, I know this is for the stage, but having a tiny dot draw or stamp itself is more practical than having the stage draw. It might confuse some new Scratchers who don't know much about complex math. I like the "draw circle with radius" idea, though. I support.

What complex match is involved in drawing a dot on the screen or drawing a lin/rectangle/circle between 2 points?

Your "floodfill" and rectangle blocks confuse me. A rectangle has four points, so how can you draw it with two? Also, some people don't know what a radius is.

I dont think these blocks are necessary but I would like the "flood fill" block.

Actually, this will be too easy to do in 2.0; they have a warp block that atomically preforms the script it contains, and so, it'll be easy to do tools like this with a hidden sprite and the pen.

This topic was made long ago. Before anyone knew about the warp block, and hardly anything about 2.0. So no one could have thought of this.
