Final Project immediate help Please!!! due January 16th

[Shainman]

I'm almost done my final project for my grade 9 computer class. My final project was to create a game of my choice so i created City Jumper. I have almost all of my program complete, but i ran into a big problem, I dont know how to do collision detection. the stickfigure jumps over the buildings (bmp files) that have a border around them (only the first level has borders). I really don't know how to make it so that when the stick figure hits the buildings he looses a life and has to start over. This is my code, any help is really appreciated.

%This Program will let you play a game called City Jumper.
%You play as a little man who jumps over buildings to get to the end of the level.
%There are a total of 10 level that you have to complete.
%You will have 3 lives to try and finish the game.

Turing:

if box1_x2 > box2_x1 and box1_x1 < box2_x2 and box1_y2 > box2_y1 and box1_y1 < box2_y2 then         put "They have collided!"         exit     end if

For Rectangular Collision

If you want Circular Collision

Turing:

distance_between_centres := sqrt ((circle_2_x - circle_1_x) ** 2 + (circle_2_y - circle_1_y) ** 2)       if distance_between_centres <= circle_1_radius + circle_2_radius then         put "The circles have collided!"         exit     end if

Thank you richcash for your awesome tutorial on collision, which has helped me a lot.

[Shainman]

what if i need to do collision detection between a cirlce and a box? like if i need to know when a circle has touched a box.

[Tony]

here's a hint - draw it on paper first

[Shainman]

wow that actually helped ( the paper thing) thanks Tony!!!

[Tony]

no problem! I knew I was writing all that stuff for a reason

[questionableninja]

WTH all my teacher lets us do is stupid projects that are no fun at all like making a pargraph out of 3 files like WTF is that maaaan you are so lcuky *sigh*
