How to pick random points within radius

[Melonslise]

I want to be able to pick random points within a certain radius of a point much like the "Pick Units In Range" trigger. I am fine with either jass or gui.

• Var_Real_Random_Angle = Math(random(0, 360))
• Var_Real_Random_Distance = MAth(random(0, 1000))
• Var_Random_Point = Offset by angle and distance(Var_Real_Random_Angle, Var_Real_Random_Distance) from Var_Centre_Point

This is close to how it should look in GUI. No WE underhand so syntax may vary but you get the idea.

Thanks. Although I'm pretty sure that isn't the most accurate way since the angle is an integer and some points will probably never be picked especially at bigger radii. Are there any other ways?

You could do the math yourself lol. Is it worth the trouble though for some accuracy ? Perhaps.

Pseudo code:
Get a randomized angle
Get a randomized distance
Get X of start point
Get Y of start point
X of end point = X of start point + (dist * cos(angle))
Y of end point = Y of start point + (dist * sin(angle))
Set end point X
Set end point Y

Some of those would be custom scripts like Set X for point
Also, sin & cos in war3 may or may not work in rads instead of deg so you may or may not have to do a conversion of the angle or use it as rad from the beginning

I see thanks. Looks like jass will be handy here. Is this way any slower than just picking a random point in region with a native function?

I guess nedio95's first method also works with a real.
