If you're asking how to make Scratch physics realistic, it's pretty complicated.

Depending on what type of physics you want (gravity, water simulator, bounce and weight, ect…) there's a lot of different blocks needed to do so. Can you be a bit more specific on what type?

I want gravity and water for my new game.

Gravity is generally not too hard. Have y-velocity and each time through your main control loop subtract a value for gravity. For example, if you jump and set y-vel to 8 and have gravity as -2 your sprite would go up 8, then 6, then 4, 2, 0, and start falling -2, -4, -6 and so on.

Need more info regarding water. If you just mean a sprite is moving through water then you just need to reduce gravity and slow down x movement more quickly.

Gravity is always easy in games, but realistic physics is very difficult, so I have never bothered to try it out. If you want a simple physics engine, you can look at @funut's yt tutorial. If you want a more advanced physics engine, tutorials for them are available online, but they are in different coding languages, so they can be a bit difficult

As has been said, gravity is relatively easy, water on the other hand isn't unheard of but certainly is a challenge. Water is something I could try to think but would require clones, tons of variables and hours of thought and trial and error.

I'd suggest either watching a couple tutorials on it, see if it's something you'd wanna include or just don't really do it and just have a basic blue costume, something like that.

Does your water need to flow like terraria or do you just need the physics of being in the water

wow this is old

when green flag clicked
set [ v] to []
set [ v] to []
when this sprite clicked
if <touching [ v] ?> then

end
