ok what if we did something like this:

we make two images, put the black stuff into one and the red into the other

once either is collided then we use inequalities to check which of the four possible directions are likely, then adjust either one or both of the movement variables (depending on if it was a corner or side collision)

sorry if the image turns out weird

My method was to check the difference between the centers of the ball and the colliding brick in both the x and y direction. I then subtracted half of the brick size in each direction from the difference. You can then check to see if the ball is hitting the top/bottom or the right/left. I never fully developed it, but it seemed to work pretty well.

so if:

ballx>(bricks left side) and ballx<(bricks right side)

and

bally>=(brickcy)-(.5*16)-(.5*10)

then

top collision?

eh worth a try, Ill hop to coding


IS ANYONE ELSE WORKING!?!?!?!

IF YOU ARENT SURE OF YOUR PART JUST ASK, WE NEED PEOPLE WORKING!!

I don't know how many people are left Ashingda left a while back, not sure who else was part of it though.

Just to clarify the math:

If the brick is 30 pixels tall by 40 wide:


I didn't try out the flip both in my code, it just popped in there when I was typing this. That is so that if it hits the corner of the brick it will change direction both ways.

can you kinda clarify the math?

i get everything up until the if, but it seems like a top collision would be represented by y<=5 and bally<brickcy and that a bottom would be y<=5 and bally>brickcy

The brick is 30 units tall and 40 units wide

So that means that the ideal difference between the brick center and the ball center is half of that (15 units up or down and 20 units right or left).

Basically it checks to see which offset is closest to the ideal case (15 and 20) by figuring out the difference between the distance itself and 15. Whichever is closer to 0 is treated as the collision case.

I just noted some ways to possibly improve it:
-Add an extra abs value around each equation, in case the difference is less than the ideal case (or to the if-then like so
If abs(y)<abs(x)...

if we decide to go to 3d things just got easier, Josh Mooney has been doing a 100 models in a 100 days project over in the 3d board and he just made a pong paddle and pong ball as models

the best part is I never even asked him to, he just did it of his own free will!!

I don't think quitting is the right answer. Perhaps just polish version 1 and say its done.

I'm still here wanting to learn.

And for the collision thing could'nt you make the levles useing
data.You would just set it up like a grid like 10x and 8y.



Zero for no brick and 1-10 for the other bricks then read the data into arrays(10,8).Then for collision you just depending on where it is (the ball) do somthing to array(x,y) if it's >0.

Looking at page 4 I see that you have 4 bricks, so on the data thing you could have 4 diffrent balltypes.

0= no brick
1= 1 hit
2= 2 hit
3= 3 hit
4= can't be destroyed

So you can do what you guys did on the second project for the faces
just
if balltype<4 then balltype=balltype-1

This will change the image and the number of hits needed.

Data is a bad idea (sorry).

Better would be to use an external file that is read the same way as the data.

Why is this better:
-Easier to add levels/remove levels (just take them out of the file
-Easier to edit levels (can make an editor or whatever that outputs correctly)
-Neater code (don't need blocks of data statements
-Allows for future content release (not a big deal here, but should be considered on all projects). With data you would have to update an entire exe

All in all it is better, especially since reading from a file and reading from data are very much the same

I was thinkin the same thing bn2

also we are guna use -1 for the indestructible bricks, cuz in ur methos we also would need a check to prevent the vtrength from going negative, meaning 2 checks, if we use -1 for indestructible then we just need one check

YYYYAAAAAAAAAYYYYYYY, i fixed the collision!!!!!

I guess our main problem was using sprite collision() instead of sprite hit(), my theory is that when two sprites first hit, it doesnt trip the collision, only the hit

the second movement of the ball would trip the collision, and by then it was possible to have blown through half the ball and tripped multiple collision spots, causing the problem

so a simple switch to sprite hit() solved the problem

so yeah feel free to download the newest version on the first post

well the collision is better anyway, further research shows that there are still a few bugs

also do we want to leave it so that if you hit a corner you will essentially bounce back in both x and y axis or do we want to change it?

are you incrementing in your checks instead of adding the whole amount? i.e


Have you got the menu into a subroutine so the game can be paused?
I managed it but it was a lot of work because there were a lot of things relying on code that was redundant when switched to a subroutine.
I noticed a lot of that in this program; code is stuck to its current position because it relies on code from other places. With experience you will learn to make blocks of code as independant as possible so they can be called many times or moved, without breaking the program.

hadnt thought of incrementing the balls movement one pixel at a time, checking fr collision each move, that would make things work much better, thanks obese!!

and yes the menu is a subroutine, but I havent tested jumping to it from the main game

ok i added obese's collision idea involving a step-by-step movement and the game LOOKS better, its tripping the collision the instant the ball hits the bricks rather than going into them slightly, but it doesnt work any better

the two key problems im encountering are:

1) every so often the top of ball collision is ignored and the ball flies through all the bricks, destroying each one it hits

2) for some reason sometimes if the bottom of ball or right of bal collisions occur, both trip, so if the ball hits the top of a brick then it always goes up and left, regardless of if it was going right when it hit the brick

any ideas?

the collision im using is the same as the one in the first post, the only change I have made is the addition of the step by step movement

I found that too I think it is a problem with the collision detection or the get_brick function. One or both are checking the area incorrectly eg if x<xmin and x>xmax instead of if x>xmin and x<xmax

PROBLEM SOLVED!!!!!!!

u were close obese, it was the get_brick function but not that problem

i never implemented a check to see if the brick number it returned still existed, so what was happenin went something like this:

in a situation such as
ddd
ddd
d-d

where d represents a brick, if the ball hit the center brick from the bottom (where the crater is) when we checked for a bottom collision it would register the destroyed brick as a bottom collision and keep moving up

a similar problem occured for the other problem

i have updated the first post with the working version and have added a Media Numbers .txt file for easy checking of what image number a brick is, what sprite numbe the ball is, etc

ok on the noobs wanted thread BB posted a score font, so now im off to get that implemented

Great, get that implemented. Hey, I made my own version of fullscreen mode, if anyone's interested. It retains the bitmap and everything when you switch between windows, it uses the full resolution of your monitor, and Alt-Tab works instantly! Feel free to use it. It's really cool.

i have worked out a system for externally saved levels, and will begin production of a leve editor tomorrow

i need to know though if we wish to encode the external level or not, meaning do we want to be able to open a level data file in notepad and view it, or not?

for those of you who havent ever used file access, I suggest you read TDK's 4th tutorial on file access

The zip does'nt work for me.

When I run the code it says "image does not exist" which was the main menu image so I downloaded that and put it where it belongs.

But now it says "file does not exist" and it's just highlighting the "LOOP" part of the code.So is everything I need in the first post zip?

I would suggest yes, just for quick editing of levels (in case there is something wrong). Keeping it straightforward will keep it easier to manage.

sorry for trip post

ok new update

the main proram now works based off external files

i have removed that lengthy load_level subroutine and made a loadlevel function

IMPORTANT!!

if you wish to see this in action, follow these directions

download and extract the zip, same as always

DONT RUN THE MAIN FILE YET, instead run the external level test .dba file, this creates an example of an external level file

check to make sure that the levels.txt file was properly made, open it if you like

the format for each level in a file is as follows:

first the level header which is an l (L) followed by a number, this is the level number, so l1 is the header for level 1

next the number of bricks in that level (theoretically 182 bricks can fit into the screen minus the border)

then the actual brick data, each of which is made up of three pieces of data: brick type (1-3 for now), brick coordinate x (center i believe), brick coordinate y; in that order

then the level ends with a ;

so once you have ensured the file was created and is in the same folder as the DNG4.dba file then go ahead and run that

I don't see the need to encode it. Encoding it does several bad things and a couple good ones:

Good:
Keeps people from messing with your stuff

Bad:
Keeps people from adding onto your stuff (keeps the game alive after you don't continue support)

Bad:
Makes it a requirement to have and make a map maker. If it is encoded, only you can do it.

If you want an easy way to kinda do both:

Use a fileblock to encode each one. That way, it is really easy to get at (just read it out) and you can keep it encrypted. You could write a program that would take the file and enter it into a new fileblock so that if people make something, they can convert it and that way they can't get at your stuff.

i meant encoding as in using the built in read byte, read word, etc commands, not anything fancy thats hard to figure out

also do u think in the level editor we should make it a free place system, where you could place bricks anywhere, or limit it so that you can only place them in certain spots, or maybe try and do both?

I would suggest a grid type deal, turning a grid coordinate on or off for a brick.

If you have time and motivation a free place system could be good, but I imagine it would be tedious to try to get a straight line of bricks

right that was the point of the question

ive not got much if anything going on right now so im doing a lot of coding

ill start with the grid placing system then maybe add a free place system option for when you want to do a special design of bricks or watevr

is it just me or did this project start with like 5 members and 3 advisors, then go down to u and me?

seems like. I am not even officially part of this one, just in my free time when not working on my game for that one competition I pop in.

Don't forget about razer though, he is still floating around waiting for something to do.

ur either in the wrong thread or said the wrong name BB

ok go view the first post

a simple level editor is now included, nothing fancy

click on the grid to place bricks

mouse wheel to change bricks (only 1-3 hit blocks are currently utilized)

enter/return to save the level, if the levels.txt already exists when you try to save then it will tell you so and return to the editor, no work on the current level is lost

HOWEVER!!! once you hit enter the level is saved and the program ends, you cannot load a file (yet) so be aware of this once you hit enter

i plan to continue work tomorrow, but tonight im beat and going to bed

tomorrows plans:

load file button, nicer looking GUI, multiple level functionality (this is already implemented into the main game, but not into the editor)

that last task reminds me, should you make a level and complete it in the main game, you will enter an endless loop and must f12 out

YAAAAAAAYYYYY the team is slowly regenerating!!!

a lot has happened since u left, heres a summary of the main chages:

changed collision over to sprite hit() rather thsn collision, also made it loop through each pixel of motion rather than just check the end result of the move

added score system with custom score font

changed the level making over to external files (deleting you're levels, sorry)

made a level editor (not finished but working)

right now just try and familiarize urself with the mew programs, then let me know when you are ready for a job
