LUA snippet to calculate a point between 2 coords

vec.lua

function getPointOnLine(vec1, vec2, point) --the point on the line [point is always smaller then the distance between the 2 coords] (to get the coords on the center, just divide the distance with 2)
distance = #(vec1 - vec2) --distance
vec3 = vec1 + (point/distance) * (vec2 - vec1)
return vec3
end
