Help with collision detection

[jedi-bob]

i cant get the oval collision detection working, i will post the code, if i could get some help that would be great. I copied the oval collision detection code into my program, but it get errors. I am using Turing 4.0.4c


var chars : array char of boolean
var A1,B1,A2,B2: int
var radius1,radius2:int
A1:=50
A2:=10
B1:=50
B2:=10
radius1:=10

loop
drawfilloval(A1,B1,A2,B2,7)
Input.KeyDown (chars)
if chars (KEY_RIGHT_ARROW) then
cls
A1:=A1+15

elsif chars (KEY_LEFT_ARROW) then
cls
A1:=A1-15

elsif chars (KEY_DOWN_ARROW) then
cls
B1:=B1-15

elsif chars (KEY_UP_ARROW) then
cls
B1:=B1+15


end if
delay(100)
drawfilloval(200,200,50,50,yellow)
drawfilloval(200,200,10,10,black)


var distance := ((A2-A1)*(A2-A1) + (B2-B1)*(B2-B1))**0.5
%you take the square of differences of X coordinates and add
%a square of differences of Y coordinates then take a square
%root of the sum
%%%%%%
%I did (x)*(x) instead of x**2 because exponents is a function
%and it takes up more resourses then *, thus its faster
%Also **0.5 is the same as sqrt() - learn your math guys

if distance < radius1 + radius2
%might be a good idea to save radious1+radious2 as const/var
then
collision = true
end if
end loop

Mod Edit: Moved it to the right forum, don't post in tutorial next time when you have a question.

you could use whatdotcolor for your collision detection....but if you dont do it correct(according to dodge), he'll get mad

[jedi-bob]

i don't quite understand. Maybe you could copy my code above, correct it, and repost it. I am very new to turing, so don't think i am retarded.

you can't expect to paste some base code at the end of your program and expect things to work

see the collision = true line? thats where you place the code that does whatever after collision occurts.

replace that with put "collision occured" to see if the code works

thanks, sorry for me being a dumbass
