Arghhh, I can't find anything in the API documentation, I am either blind or to exited ;)

Problem: I am having a object that is rotating. I do need to read the angle of the object, is it possible?

E.g: local Angle = myObject.angle

Joakim

myObject.rotation

I tested that but it only accumulates the value...so I can end up with a value of a couple of thousand...or should I divide it by 360 to get the accurate angle?

Joakim

you can set up a function that will restore rotation to 0 if 360 was achieved...

Yes, but the question is - how do I calculate that when the function is acumulating the value?

Joakim

like that, i did something like that long time ago)

1
2
3
4
5
6
7
8
9
10
11
12
13

local function rotate()
 
obj.rotation = obj.rotation + 10
 
if obj.rotation >= 360 then
obj.rotation = 0
end
 
print("this object rotation is: ".. obj.rotation)
 
end
 
Runtime:addEventListener("enterFrame", rotate)

or you can just do
object.rotation = object.rotation %360
after you add or subtract from the rotation

1 2 3 4 5 6 7

function Loop() object.rotation = object.rotation +1 object.rotation = object.rotation %360 print(object.rotation) end   Runtime:addEventListener( "enterFrame", Loop )

what does % symbol do?

% = modulus. in this case it limits the range of the rotation to values from 1-360

wow, great to know, definitely useful little symbol)

Woww, thats so great...I have to look in the API documentation about this. Works perfect, just tried it. Big thanks!
