Hi guys! So I'm trying to make a game based off of a story that I thought of about a virus that spreads through a dumb trend about licking toilet seats, and I've been trying to make the monster sprite appear randomly on the screen. I managed to do that but then I realised it would be impossible to hit them because since there's a border that I made teleport them to a random place on the screen at the bottom, it would just spawn there it would do that instantly go somewhere else, making it impossible to hit. So I've decided that I needed to make them spawn randomly at the top of the border so it can move downwards.

Please don't leave a text explanation, I understand better when you show the script, thanks!

when I start as a clone
go to x: (pick random (-240) to (240)) y: (180)

Ok so, I'm trying to make the characters spawn at a random position at the top border of the screen you play on.

You're still not giving any real details of your problem though! It's hard to help if we don't understand the question.

@gtoal gave you a method to get a random position at the very top of the screen. If you want the y position to vary as well but within limited values just use a similar random block for the y.

y goes from -180 (bottom ) to 180 (top). x goes from -240 at left to 240 on the right. Try moving your mouse and watch the coordinates change under the Scratch screen.

If you want something to go to the very top of the screen setting y to 180 will do that (assuming the costume is properly centred) but if you want it to be randomly between y=160 and 180 you need to tell Scratch that.

OMLL. I DID IT. I'M SO HAPPY THANK YOU SO SO SO SO SO SO SO MUCH!

DEFINITELY PUTTING YOU GUYS IN THE CREDITS!





-oh wait, but now i have another problem- This one might be a bit more simple, but how do I make a wall that a sprite can't get through?

move (5) steps
if <touching [wall v] ?> then
move (-5) steps
end

Standard method which generally works is move the sprite, check if it is touching the wall (touching sprite is better than touching colour) and undo the move if so. That happens quick enough that you don't see the move.

move (5) steps
if <touching [wall v] ?> then
move (-5) steps
end

All you need is a loop around an if block that detects touching and checks the costume number. I suspect @asivi is right though, spend soem time learning more of the basics.

I'll probably try doing the practice stuff, but can you show that in block form please?

if <<(costume #) = []> and <touching [ v] ?>> then

end

But this is fairly basic given I'd already told you what to check for - try not to need things being presented in blocks, be prepared to think it through and work things out. Above is an ‘if block that detects touching and checks the costume number’ as previously suggested.

A single block out of context tells us nothing really. We'd have to see the project, see what kind of loop this was in, check the loop was running etc etc.
