How to make something move in a circle without rotating it

Wrxth

hey im trying to make a game and i need help making my sprite move in a circle without rotation so it doesnt look wierd and i was wondering if anyone knows a NOT super hard i repeat NOT super hard way to do it because i want to understand how it works so i can remember it for when i use it next
thanks!

if you dont want it to rotate the costume, just set the rotation mode to {dont rotate} while making the circle

set rotation style [dont rotate v]

if you don't want to use the rotation style, you could use a direction variable and move in that direction using trig

probably the most intuitive way to rotate a sprite in a circle would be to

set [dir v] to [0]
forever
rotate // make sure to check the box that says "run without screen refresh"
end

define rotate
go to x:(x of midpoint :: #969696) y: (y of midpoint :: #969696)
point in direction (dir) // points in the current direction of rotation
move (radius :: #969696) steps //  moves the radius
point in direction (90) // returns to the normal direction
change [dir v] by (speed :: #969696)    // changes angle

You can replace the grey boxs with the desired values

One example would be:

set [dir v] to [0]
forever
rotate // make sure to check the box that says "run without screen refresh"
end

define rotate
go to x:(50) y: (50)
point in direction (dir) // points in the current direction of rotation
move (50) steps //  moves the radius
point in direction (90) // returns to the normal direction
change [dir v] by (3 )// changes angle

I recommend playing around with it for a while to get comfortable with it.

i said without rotating the sprite i want it to orbit the center of the screen without rotating the sprite

edit: sorry i didnt see the thing that returns it to the normal direction ty

There's another way to do this with a little math that's a bit more complicated:

Set x to (RADIUS*Sin(ANGLE))
Set y to (RADIUS*Cos(ANGLE))

So one simple program that does it is:

Set angle to (0)
Forever {
Set x to (10*Sin(angle))
Set y to (10*Cos(angle))
Change (Angle) by 10
}

This is the most easiest way I know.
Here is the script:

when green flag clicked
set rotation style [don't rotate v]
repeat (100)
turn cw ((360) / (100)) degrees
move (. . .) steps
end

I am not sure about the others, but if you want the whole program NOT to rotate the sprite, this will be the script you could use.

i said not comlicated or hard @joaolmkimbr
