problem with the camera, player not being able to look at the mouse

[Yani354]

there is probably an easy solution of that, but i can't find it.
The problem is that i have set the camera to look at the player and the player to look at the mouse, but
mouse X and the mouse Y are not updating properly

The main problem is you weren't taking the player position and camera translation into account. The below in the draw method your player class draws the player facing left or right and a small square from the centre of the player in the direction of the mouse.

Code: Select all

    
local mx = (love.mouse.getX() + self.x - (love.graphics.getWidth()/2))
local my  = (love.mouse.getY() + self.y - (love.graphics.getHeight()/2))

local dx = mx - self.x
local dy = my - self.y
local dist = math.sqrt(dx*dx + dy*dy)
local normdx = dx/dist
local normdy = dy/dist

if dx >= 0  then 
    love.graphics.draw(self.playerRight,self.x,self.y,0,1,1,32,60)
else
    love.graphics.draw(self.playerLeft,self.x,self.y,0,1,1,32,60)
end

love.graphics.rectangle("fill", self.x + normdx * 96 - 2, self.y + normdy * 96 - 2, 4, 4)
