Degrees' Speed

[Mabaet.Baet]

Hi there...

I'm making a test here: Makes a unit go round from a certain point.
like this

The speed I make here is by degrees.
e.g Every 0.3 sec it move the unit 2degrees(the center dot) more. So the greater the degrees moving value, the faster it spins.

But... I want the speed to be wc3 movement speed not degrees.
I want it to move 1050 movespeed per sec... going round and round. How is that?


Sorry about my English. I hope you understand.

Edit: I think I still need this to use degrees for this??? But I'm going to convert the movement speed to degrees? Help.

• Set var_ArcLength = (var_Distance x (Radians(var_Angle)))

var_ArcLength, var_Distance and var_Angle are real variables.

var_ArcLength is basically the distance you travel from point A to B, along the edge of the circle.
var_Distance is the distance from the center of the circle to the edge.
var_Angle is the number of degrees that your unit moves in every instance of the trigger.

If you want to reach 1050 movespeed per second, (var_Distance x Radians([1/ 0.3] x varAngle) should be equal to 1050.

I hope this isn't too much math.

To try explaining it the opposite way, wc3 movespeed is equal to distance traveled in 1 second. So if you want to spin around a point at 1050 movespeed, and you are adjusting position every 0.3 seconds, you want to move 1050*0.3=31.5 distance each time. Then you can find the angular adjustment needed to equal 31.5 using Kaerf's formula: 31.5 = DistanceFromCenter * AngleAdjustmentInRadians.

In other words, you want to add ConvertRadiansToDegrees(31.5/DistanceFromCenter) to your angle every 0.3 seconds to move around a point at 1050 movespeed.

(There is a built in function to convert Radians to Degrees, but it's just multiplying by 180/pi).

That is really helpful. Thanks guys :3 +rep
