Collision Detection http://www.allegro.cc/forums/view/591420 Allegro.cc Forum Thread matthew@allegro.cc (Matthew Leverton) Thu, 31 May 2007 01:03:31 +0000

Sorry that It's a mess I'm very new to it. I'm trying to crate air hockey, but I'm stuck at getting things to collide. Can i have suggestions please. NOTICE: My Playerone and Playertwo are not images they are text essentially. '+'

Thanks guys.;D

Generally, when pasting source code its nice to encapsulate them in [code] tags. Like so: 

<code>
void foobar(int);

int var = 5;

foobar(5 * 2);
</code>

I said I was a noob. Thanks but how does this help my code????

Because then people will actually read your code and possibly even try to help.

He's right, I really don't want to read it myself. Fix it up and I might take a look. Yeah, I know, it's not really nice, but I just can't stand to look at that conglomeration above...

There's no point at the moment of doing any collision detection - you're writing the line "Air Hockey" where the puck should be, and drawing the puck at a fixed position.

Once you get round to the collision detection, have a search for bounding boxes.

]]> no-reply@allegro.cc (HardTranceFan) Fri, 18 May 2007 07:06:53 +0000

You should draw the puck at the end, after the rest of the playing field has been drawn. Make sure you are drawing stuff in the right order (z-ordering).

i changed the puck to a square just for easiness. My problem now is getting it to move right( Haven't done the up and down...it should move right and left(it only goes left)) thanks guys

Use code tags, indent your code. Use braces for each and every code block, even if it's a single line.
Create a struct to hold your player data.
Create an array of this struct so you can easily add more players (and even more important: you don't have to duplicate your code).
Get rid of the ";" after END_OF_MAIN

Oh, and use speaking variable names.

I'll say it too - there are posting protocols. Ignoring this advice is breaking one of them. Please update your post and use the [code]...[/code] tags.

I'll help this time, but no more if you don't use tags.

1. Use meaningful variable names. It takes ages to work out and remember what a, b, c... x, y are all for. Use names like xPuck, yPuck, xPlayer1, yPlayer1, xPlayer2 etc. It makes the whole thing easier to understand. [edit]Or, as spellcaster pointed out, use structs with meaningful names[/edit]

2. The line (x==a&&x<c&&y<=b&&y>=d) is wrong, and is why the puck won't go right. There is never a situation when the player position will be above and below the puck at the same time, and x==a is not the test condition you want to perform.

]]> no-reply@allegro.cc (HardTranceFan) Fri, 25 May 2007 02:28:07 +0000

How do i do the code tags again?
Is it ... at the start and end respectively?
Also, I'll change the variables.
ALSO, I dont know how to do 'structs', sorry I'm such a noob.
thanks for putting up with me

A much nicer view ;).

btw, what's the problem?

ran your game but i don't know what should work and not..

Well what It Is, Is that I cant get the puck to move the way i want so i don't know what i should do..can't find any help anywhere except here. By the way im on a deadline, this is a school course...I'm dumb!.:)

Here is an allegro pong tutorial, which you can adapt to 4 way movement and collision detection.

Sorry but, Im not sure what i should do with it...is there nothing you would suggest for my code?

]]> no-reply@allegro.cc (zavirax) Tue, 29 May 2007 20:02:34 +0000

I suggest you don't create the buffer in the main loop and not destroy it. That is a massive memory leak.

but I'm stuck at getting things to collide


Just use this:

inline bool collide(int x1, int y1, int x2, int y2, int xx1, int yy1, int xx2, int yy2)
{
     if (x2 <= xx1) return false;
     else if (x1 >= xx2) return false;
     else if (y2 <= yy1) return false;
     else if (y1 >= yy2) return false;
     else return true;
}

Sorry, my bad - the page I linked to and my suggestions didn't match (there is a link to the pong tutorial down that page if you looked). Here is the correct link to the pong tutorial.

Yeah I already found It on there, don't worry about It.

btw how would i use that boolean expression thing, could you show in my code please. thanks

Here's my code so far i can push around...any ideas how to make it slide so i only have to hit it not push ... also how would i get it rebound of the sides ... also how can i make a hole in the outside of the field so that it can go in the goal... and also ... however i think i know how, how can make a scoreboard?

lots of questions hehe sorry to be such a stupid person.
