Hi,
here is what you can do. Put this into the player:update:
Code: Select all
local stepsize = self.s * dt
local deltax,deltay = self.dx - self.x, self.dy - self.y
local distance = math.sqrt(deltax^2+deltay^2)
if stepsize > distance then
self.x = self.dx
self.y = self.dy
self.state = 'stop'
else
self.xv = deltax/distance*self.s
self.yv = deltay/distance*self.s
self.x = self.x + (self.xv * dt)
self.y = self.y + (self.yv * dt)
self.state = 'move'
end
To prevent "overshooting" the target, I first calculate the stepsize, the player can make (speed times dt). If the distance from the target is smaller than that, assume the targets position and stop, otherwise, safely move towards the target.
(I also turned around the order of calculating the velocity and applying the velocity. The velocity should be calculated first and then applied. Otherwise, you use the velocity from the previous timestep)
