Movement Broken (Went too deep?) - Top Down View

[WazMeister]

Hi All (again).

 

I must of got too cocky with programming my movement, I wanted to get an understanding of diffrent approaches and implement a state etc.  I used the Darkness awaits player template for movement and tweaked it for my liking.. to learn and understand.  It never really worked, player just moved on the spot and animation played. AFter playing some more, I strted refrencing the tird person script for help and understanding.... then finally back to my original code I used before (which sort of worked).  Now i have the player turning on the spot (the effect I want) but he still wont move at all.. just plays animation for forward and back!

I thought I understood the code, but now I'm ripping my hair out with frustration, Tried using entity:Move command and entity:SetInput but it just wont fix it!

Would someone be able to review my code below and see where I am going wrong?!?!?

Got it working by changing the movement code  around and likely more basic...  Not sure if it's the right way or best way to do this, but it works I guess...

unction Script:UpdatePhysics()
	--blank vec3 variable for later adding key presses movement.x, movement.y and movement.z
	local movement = 0
	--Get the Game Window
	local window = Window:GetCurrent()
	local changed

	--Check state for player dead
	if self.currentState == self.state.dead or self.health <= 0 then return end
	
	--Check if carrying, if not then player will be idle state
	if self.currentState ~= self.state.carry then
		self.currentState = self.state.idle
	end

	--Detect if grabbing a bin
	if self.currentState ~= self.state.carry then
		local docarry = false
		if window:KeyDown(Key.Space) then 
			self.currentState = self.state.carry
			--self.attackstarttime = Time:GetCurrent()
		end
	end

	--Movement
	--Code for detecting key presses for movement and attacks
	if window:KeyDown(Key.W) then movement = movement - 1 changed = true end
	if window:KeyDown(Key.S) then movement = movement + 1 changed = true end
	if window:KeyDown(Key.D) then self.entity:Turn(0, 3, 0) change = true end
	if window:KeyDown(Key.A) then self.entity:Turn(0, -3, 0) change = true end
	if changed then
		if self.currentState ~= self.state.carry then
			if window:KeyDown(Key.Shift) then
				movement = movement * self.RunSpeed
				self.currentState = self.state.run
			else
			movement = movement * self.WalkSpeed
			self.currentState = self.state.walk
			end
		end
	end

	self.entity:Move(0, 0, movement)
