WALLS

[jedi-bob]

how can i make it so my player controlled cirlce cant go through walls?
I checked the collision detection tutorial, but the rectangle one was to hard to figure out (it was poorly explained), and the oval detection only says when they hit. now help out, theres some bits in it for you.

use whatdotcolor and STOP POSTING STUPID QUESTIONS WITHOUT CONSULTING UR COMPSCI TEACHER AND THE TURING SOURCE/TUTORIAL SECTION

[jedi-bob]

what the hell is whatdotcolor, and how would i use it for my walls, also maybe you missed it but i said i checked the tutorials and it was poorly explained.

[Thuged_Out_G]

whatdotcolor is used to check the color of a specified pixel.

use it like this

if whatdotcolor(x,y)=10 %where 10 would be the color of your box
then ballxdir:=-ballxdir
end if

all that does is, if the x and y coords of the ball hit the color 10, then reverse the direction of the ball

or without whatdotcolour...

code:

if ballxdir > maxx - 30 then     ballxdir := -ballxdir end if

[jedi-bob]

i just want my ball not to go through the walls, not to bounce in a different direction (its not animated, it keyboard controlled) i just want it to stop, not bounce.

Hey there Jedi-bob its me Jedi-Jim

[jedi-bob]

i haven't talked to you in along time, here have a bit.

[Jedi-Jim]

don't worry BOB they can't prove the little girl was telling the truth

[Cervantes]

code:

if ballx > maxx - 30 then     ballxdir := -0 end if

comon man with the info we gave you you could figure out how to do that...

unless...

do you know what ballxdir means??

That seems a lot like him trying to command us to help him....who would like to help someone who is commanding you to do something??? And you have barely any bits anyways, so bleh. Me, being the nice guy I am, will teach you the dark arts of the:
"whatdotcolor"

code:

var x, y, xmod : int := 200 xmod := 2 loop     setscreen ("offscreenonly")     View.Update     Draw.FillBox (0, 0, maxx, maxy, 0)     delay (2)     Draw.FillBox (500, 150, 600, 250, black)     Draw.FillOval (x, y, 20, 20, 12)     x := x + xmod     if whatdotcolor (x + 21, y) = black then         xmod := 0     end if end loop

This code will move a ball, but when it hits the wall (which is black)...it stops. whatdotcolor is used like this

code:

whatdotcolor(x,y)=color %(x,y)='x' and 'y' co-ordinate its checking what the dot color is at %color= the color of dot its checking for %soo..... if whatdotcolor(x,y)=red then put "AHH!! The whatdotcolor of x and y is red!!!" end if

Understand??? Now ASK NICER next time!!
