Collision Detected [Lua + Löve]

[Bambo.]

Hey I posted this question a while about in the "What do you need help with" thread but i got no response, so i hope you don't mind if i ask here.

I'm having alot of trouble with collision detection with Lua + löve, i know there are things like this [url]http://love2d.org/wiki/HardonCollider[/url] but I'm unsure on how to make it check collisions if there alot of objects.

the furthest i get is between two objects, if i can get this working i can actually start making some games haha, thanks.

Here is my best shot... [url]http://dl.dropbox.com/u/15805077/perma/Blocks.zip[/url]

So.. what exactly is your question or problem?
Your little game seems to be working fine.

I suggest you don't rely on a library that much but instead do your own collision detection and actually understand what's going on under the hood:

I am currently on the way to reproduce this method by purely using vectors, but damn it's complicated shit.
I'd suggest you get box-on-box-collision working first.

If you want to see my rather modest try at implementing it, you can check out my sourcecode: [url]http://dl.dropbox.com/u/28079852/PlatformerProto14.5.love[/url] (just rename it to .zip and unzip it)

I'm guessing you haven't looked at many Love libraries.

Wow never noticed that.

This is the best I can do really

function CheckCollision(box1x, box1y, box1w, box1h, box2x, box2y, box2w, box2h)
    if box1x > box2x + box2w - 1 or -- Is box1 on the right side of box2?
       box1y > box2y + box2h - 1 or -- Is box1 under box2?
       box2x > box1x + box1w - 1 or -- Is box2 on the right side of box1?
       box2y > box1y + box1h - 1    -- Is b2 under b1?
    then
        return false
    else
        return true
    end
end



for k,v in ipairs(mobs) do
	v.pos.x = v.pos.x + 1
	if CheckCollision(v.pos.x, v.pos.y, 10, 10, player.x, player.y, 10, 10) then
		player.health = player.health - 5
	end
end

May I suggest you create a box/rectangle class, and that you just pass that into the heck collisions instead of the x, y, height & width of each box

Ah thanks, but is this the only way i can do it?
it seems kinda bad.

As I believe you completely ignored my post, here is the link again: [url]http://www.metanetsoftware.com/technique/tutorialA.html[/url]

It's fairly easy to implement.
