Coin keeps spazzing out when collision code is added

Post by l0ki77 »

Hello I've been trying to make a game for school and every time I add collision detection code to my project my object which is a coin keeps spazzing out without the player even touching out. The coin just goes all over the screen randomly with the player having any interactions with. I've tried removing the random spawn of the coin but the score keeps updating even without the player being near the coin

I have attached a file and I was wondering how I would use code tags, sorry I'm new to posting on forums

Hi
Your coin is too big and so it collides every frame.
love.graphics.getWidth() / Height() get the size of the window.
I guess you will want to use https://love2d.org/wiki/Texture:getWidth but for testing I just put fixed numbers:

Code: Select all

function Coin:new()
  self.image = love.graphics.newImage('sprites/coin.png')
  self.x = 300
  self.y = 300
  self.speed = 0
  self.w = 50--love.graphics.getWidth()
  self.h = 50--love.graphics.getHeight()

To use code tags, you write:

[code]
the code here
[/code]

thanks i used

Code: Select all

self.image:getWidth() and self.image:getHeight() 
and got it to work but the score will increase in random increments once Collison is detected a couple of times

Ah yes. You need to do the same fix for the player's dimensions as well.
In function Player:new()
