Yes, I know what it does. That's fairly obvious. tongue

Is there a way to reconstruct that block by using other blocks, except using sprite or color sensing? So in other words, it'd be like "if touching color [ ], bounce".

I've tried it but Scratch has a weird angle system xP

Not that I know of. You could maybe make one with touching [edge] block though.

I don't want it to bounce if it's touching the edge though tongue

I want it to bounce if it's touching a certain color wink

Wow I didn't think that through.

If <Touching [Color]>
//Some really hard script most likely using the point in direction () block \\
Wait until <Not<Touching [Color]> >
{End of If}

Maybe that would work?

Yes, I have that already. tongue

I just don't know what direction to make it point in--I've tried direction + 180, direction x -1, 180 - direction, and 360 - direction, and none of those have worked. sad

This script isn't the best but;

Start
Forever If <Touching [Color]>
Point in Direction ((Direction ) + (180))
Move (//Number of steps sprite moves\\) steps
{End of Forever If}

okay so I figured out this:

where the side walls are black and the top/bottom walls are light gray.

Is there any way to get this to work with one color?

(Don't ask what the move 0 steps blocks are there for, I have no idea tongue )

This should be fairly easy to figure out: just sit down with a piece of paper and do some maths smile

Give me a second to improve this one; this seems correct, and you can judge whether you've hit a wall or ceiling by its direction and some unrendered checks.

EDIT: Got it:

Sensing seems like the easiest solution for this.

LS97 · 2011-09-25 16:34:43

I just noticed that it's impossible to use plain arithmetic to figure out the angles. Maybe some trig? hmm

I know Kileymeister already figured it out, but would this work?

For your moving scripts (if there are any) add point in direction 90 for right arrow and -90 for left. Then say if touching color and direction = 90 point in direction - 90 and do the same thing but switch the direction = to direction = -90 and point in direction 90.
