new block idea for 3.0 [rotate around x,y point]

nickliu

i think that a block should be added that can rotate a sprite around a point.

rotate clockwise () degrees around X:() Y:()

No Support, this is a simple and easy workaround:
Do this one to turn clockwise:

go to x: (18) y: (14) // or any place you want the sprite to go 
turn cw (15) degrees

Do this one to turn counter/anti-clockwise:

go to x: (18) y: (14) 
turn ccw (15) degrees

You can also choose a new enter for your sprite in the paint editor using the centering tool, to make it rotate differently.

Although workaround-able with

define turn cw (θ) degrees around x: (x) y: (y)
set [radius v] to ([sqrt v] of ((((x) - (x position)) * ((x) - (x position))) + (((y) - (y position)) * ((y) - (y position))))
go to x: (((radius) * ([sin v] of ((direction) + (θ)))) + (x)) y: (((radius) * ([cos v] of ((direction) + (θ)))) + (y)
turn cw (θ) degrees // that (θ) is the Greek letter theta.

one wouldn't expect younger users to be able to work it out easily, so support for

turn cw () degrees around x: () y: () :: motion

Plus, it's quite a long workaround.

I don't think that's how they meant by this block, I thought that this block causes the sprite to rotate (θ) degrees about the axis of rotation at (x, y), not rotate from the point (x, y).

I think they mean to orbit around that area

Semi-support- the workaround is complex however I don't really see situations where I'd use the block.

I don’t foresee much use either since most of the time you need one rotation point and can just set the costume center wherever that may be.

when this signature read :: events hat
if <I know what [kumquats] are :: sensing> then //false
have (Katty :: pen) [eat v] [nearby kumquats v] :: motion // Katty eats the kumquats for me, whatever they are
else
learn what [kumquats] are :: sensing // this block must be malfunctional
end

You cannot trust any of my posts because I am dumb. Some may be right, though.

perhaps you could use it during collision simulators perhaps like some sort of multiplayer sumo wrestling game with plane possibly like cosmoteer.

Support, although there is a block workaround, A lot of other blocks have workarounds too, very useful!

No support.

Yes Setting costume center can be a problem but use a different duplicated costume for that.
When using that type of rotation,
Switch to that costume ,rotate and switch back to old one.

I said you can do that by changing the center of the sprite in the paint editor to make it appear that it's rotating b around a different point.
you can workaround blocks with the paint editor??? Who knew???
