adding in physics blocks

Enderplays8

Can you add a gravity block to scratch? it would make platformer physics a WHOLE LOT easier. here is how it would work:

forever
if <not <touching [ground] ?>> then
repeat until <touching [ground]>
change [Y speed] by (-1)
change y by (Y speed)
end
end
end

the

<touching [ground] ?>

is because this block would add in a ground sprite into your project. it would be in a category called:
(black colour) Physics.
and, a number or text block also in the physics category called:
(scroll on sprite).
absolutely NO idea on how long it takes to enter it in in JavaScript.
NO IDEA AT ALL. also, when you add them in, (if you even DO add them in),
let me know!

This is in the wrong topic, also, no support.

You just gave a workaround, so I doubt this would be added.

use the custom block

define gravity blocks

Wasn't there supposed to be a physics extension at some point?

Anyway, I think that for simple platformer physics it's fairly easy to recreate with a simple gravity variable. (I mean, you basically gave the workaround yourself…)
And as for more complicated physics, well, would that really be used enough to warrant an entire extra main category being added?

And all the world over, each nation's the same,
They've simply no notion of playing the game.
They argue with umpires, they cheer when they've won,
And they practice beforehand, which ruins the fun!

Support.

If there was a block that said -

set gravity to (true or false)

- it would be really nice to create platformers.

Uh, no…

You can just do:

forever
if <(gravity_enabled) = [1]> then
whatever gravity script :: grey
end
end

Infrequently active.

It feels weird to see how far we've come. I hope you're well, wherever you are!

Uhh, I was just giving an example of what the block would look like?

Even if people used that script, you will have to define the variable, how it works, etc… Still giving support.

Apparently @Grifpatch has made one. It would definately be doable.

no signature plz

Not only griffpatch made a gravity system, also tons of other Scratchers and New Scratchers.

I fixed your grammar btw. ;P

GEEZ GUYS, THNX!! but, the physics blocks would just reduce lag. because normal platformers have more blocks, but the

(Gravity)

block reduces lag ‘cuz it doesn’t use AS MUCH blocks!

WELL,

Gravity

is just a SUGGESTION.
Hmm? what's that Gravity Block?

Gravity

I think scratch team should add me . there could me many uses for me, and other of my type . it looks like they have some things to say, too .

hitbox width () length ()
wall/slope detection
NPC/ENEMY ACTION # of actions ()

i'm a hitbox detector. i'll got to any sprite i'm in, and i'll be the size of my two number-or-text slots. I also don't take variables .
i'm a slope/wall detector. I detect if the player is touching a wall, or walking up a slope. I even detect ceiling collision and ground collision .
i'm an NPC/ENEMY action randomizer. I will make enemies in platformers and NPCs for simulators easy. enter the number of actions in my number-or-text slot to determine what kind of enemy/NPC it is.

so, there are some more of my PHYSICS category blocks.

hellothisisnotnew

set gravity to (0)

hellothisisnotnew

Suggestion for physics blocks:

set gravity to (0) by (2.5)

run simulation

I'm not sure if someone already mentioned this, but Griffpatch made an editor physics extension, it can be found here.

This would be very difficult to program in JavaScript, and the ST might not have the time to code something that complicated. How do you propose they will be able to do this in a timely fashion?

Support. This can be used a lot and can be great for games where they have gravity.
I also think these blocks are professional which means it can teach kids the basics of gravity in games or coding. Which is a great thing to teach children!

Although one thing. Is this going to be hard to use when you are a new scratcher? Prob is but they will learn. Maybe as an extension would be better.

I haven’t seen this post in 2 years and now I’m seeing it and its kinda old now like you can just go to a physics project and copy it
Or use a game engine with visual coding like scratch

I keep trying but if I add gravity my X movement does not work. Can anyone help me?

You just gave a workaround lol. Why would the ST add something if it had an easy workaround?
