Here is some code:
(x,y) = position of player
(x0,y0)(x1,y1) = line to check
colradius = radius of player
((X1 - X0)*(x - X0) + (Y1 - Y0)*(y - Y0))/((X1 - X0)² + (Y1 - Y0)²)->a
if (0<a and a<1 and ((x - X0 - a*(X1 - X0))² + (y - Y0 - a*(Y1 - Y0)))² <= colradius²)
then
;react to collision
end
that should check if the player collides with the given line.

Back to Cretaceous is a java game which i'm working at with a few friends. The engines are almost done, so now we have to start working at the graphical part. There is still one problem: We can't agree on how the dinosaurs wil look like, so we decided to append a poll. There are three possibilities:
 - Scales: The dinosaurs will have a scaled skin, which will make them look like giant reptiles. This is how almost everybody thinks abouth dinosaurs.
 - Feathers: Te dinosaurs will have feathers, which will make them look more like birds. Recent investigation has proved that some small dinosaurs had feathers. Weather the big dinosaurs had feathers is still uncertain.
 - A mix of the two: small dinosours will have feathers (becouse that's proven) and the big ones will still look like giant reptiles (becouse that's how everybody thinks abouth dinosaurs).

I'm not saying which one I prefer becouse that could have influence on the results, which isn't fair, so please don't ask for it.

If you want to write a music composer for the calculator, you should limit it to beebs. You can make it sound realistic, but then you'll have to fill the entire memory with saved notes from different instruments.

You can do it like the ringtone composer of my celphone: every key stands for a tone and the two arrow keys are used to make tones longer/courter (my celphone only has 2 arrow keys). Ass the specs of my celphone are a lot worse than thespecs of an ti-83+ series calc, this should be perfectly doable.

the last reply was from 2009. Does the project still look alive to you?

EDIT: ninjad

I just made this one for a project that is currently halted:


How bad it it?

After placing ret's and jumps at some positions in the code and counting the bytes in the memory editor of wabbitemu, I found out that thi routine does anything but drawing a textured quad. Amost nothing of it is doing what it should do, so I decided to put this on hold, make an other game, and try again when i'm more used to asm.

So, does anybody have a good idea for a good 2D or wireframe 3D game?

Edit: I just noticed i tripple posted, but there is more than 6 hours between those posts, so it's ok, right?

Alright, thanks for all the great info everyone Ok, get myself a 84+SE, learn BASIC, ASM, and AXE. Hone my skills, then move on to a Casio Prizm when I feel I'm ready lol
I kind of wanna paint the casing and add a backlit screen, is that a bad idea or no?

You can't do much wrong with paint, but for the backlight, I would suggest just taping some LED's at the side of the screen, outside of the calculator. This should give you enough light if you take bright LED's. Also remembr that soldering anything to the INSIDE of your calculator will void the warranty, and if you are using LED's for this, don't forget to use a resistor when you use the calc's 6v battery pack.

But anyway, i really think you should paste LED's or other lights to the front of the calculator, pointing at the screen. A screen that isn't made for use with a baklight has a mirror at the back, which usually isn't fully transparent (I tried it with an other kind of LCD some time ago, and only a rectangle in the middle was illuminated). And many other screens with baclight also have the light in front of the screen anyway.
