### Re: [HELP]Rotating circles around the middle and not corner

If you insist on 0,0 being the center of the window: w, h = love.graphics.getDimensions() love.graphics.translate(w/2, h/2) Also, you probably should offset your circles by a half too: love.graphics.draw(circle, sunX, sunY, 0, 1, 1, circleW/2, circleH/2) Lastly it's always a good idea to program yo...

### Re: [HELP]Rotating circles around the middle and not corner

That it's rotating around the upper left corner is good because it's the origin(x=0 and y=0). Just translate the origin to the desired position the way you're doing it. Or if you wanna have rotation and translation in the same line: planetX = math.cos(angle) * rotation_radius + rotation_center_offs...

### [HELP]Rotating circles around the middle and not corner

Hello everyone! I'm currently making a "solarsystem" for fun and to get a better understanding of how Löve2D works. I've just hit a roadblock in where I try to make my planets rotate around a point that's supposed to be in the middle of the screen and for some reason the rotation is set in the upper...

replace your "distanceBetween" function with this
https://love2d.org/wiki/DistanceBasedCollision

and change this line to

Code: Select all

if distanceBetween(z.X, z.Y, player.X , player.Y,30,30) then
hope that helps
I'll check it out when I have time
Thanks!

### [Help] Collision detection isn't working as it should

Hello everyone! I'm currently following a tutorial to create a "Zombie-shooting-survival" game on Udemy that I think is kinda good. But I have a problem where my "zombies" are supposed to delete themselves when they collide with the player but sometimes it works but more than often it doesn't (the z...

### Re: [help] with collision detection on a Pong remake.

Nevermind this part of the post, I moved "return ball" to the bottom of the script and at least it runs now Right now I'm attempting to use BoundingBox to try to collision and this is what I have right now: local Player = require("player") function love.load() Player:setup() end local ball = {} fun...

This is what I am using for my Pong game. It's a good basic start.
Thanks I'll take a look at it later, but how do I/does it determine the height and width of my object?

### Re: Help: Advice on how to make my ball in Pong project "bounce"

That's the field of collision and response. You need to detect collision and issue appropriate response action. You could use existing physics libraries for that, or do all the math yourself. Yeah I figured that collision detection will be the problem and Jasoco recommended that I look up Bump . I ...

### Re: Help: Advice on how to make my ball in Pong project "bounce"

Look into Bump. It'll make it easier. Otherwise you'll have to do the math yourself. A bunch of if checks on the position of the ball and the paddle. I'll take a look at Bump but right now I think my problem is to know when my ball and paddle collide with eachother. I'm thinking something like "if ...
