I have made a project where although the sprite moves a set number of steps, it's movement is modified by gravity and lift (it's a plane) so I cannot just work out it's speed by multiplying the steps.
Does anyone have any suggestions about how I could work out the accurate speed.
I have tried using the sine rule to work out a vector but it went horrifically wrong and I couldn't find any problems.

This uses the equations of motion so may help?

What do all the variables do? The speed=distance/time is what I need, but I have never got it to work

I've got it! lists are the answer!

excuse me, Bv141 but can you please explain how? im trying to use it for a game. reply ASAP

Stop making me feel old
Also, make a new topic, and you may need the distance formula.

Hello people!

I need help by measuring speed - When you move, then variable shows how fast speed it's moving.
It's for game

Thank you!

Always create a new post when you need help, this topic is almost 10 years old.

Anyway, you need to save the previous position before moving and then compare them. Make sure that you copied the expression correctly. There isn't any built-in way of measuring distance between two points, so you'll have to use trigonometry.

when green flag clicked
forever
set [old x v] to (x position)
set [old y v] to (y position)
movement scripts::grey
set [speed v] to ([sqrt v] of ((((x position)-(old x))*((x position)-(old x)))+(((y position)-(old y))*((y position)-(old y)))))

Hello people!
This is RSRCTACHPRO again
I found out!
And for these steps you will need one variable so let's call it “mouse movement”
First put when flag clicked (optional)
IMPORTANT! - Put another empty sprite. This wont work on your player's sprite
2. Put forever
3. Put Go to mouse-pointer make sure it's mouse pointer
4. Repeat (num) Make sure you put 1
5.Set to (distance to (mouse-pointer)
This is it
Enjoy! This measures how fast your mosue is moving and variable will show you

Here's example

when green flag clicked

forever
go to [ mouse-pointer]
repeat (1)
set [ mouse movement] to (distance to [ mouse-pointer])
end
end

Oops! Wrong code

when green flag clicked

forever
go to [ mouse-pointer]
repeat (1)

end
set [ mouse movement] to (distance to [ mouse-pointer])
end

Sorry for the mistake
