How sense the object ?

What is it you are trying to achieve?
<Replace all the <> with your answers/code and remove the <>>
I am trying to create a game that senses when an object flies by.

What is the problem you are having?
<Answer Here>
I can't fine a command that would sense the colour/ object?

Searched around, went into turings help reference, didn't understand it.

Post any relevant code (You may choose to attach the file instead of posting the code if it is too long)

drawbox (120,120,maxx-120,maxy-120, 1)
var x,y :int
x:= maxx div 2
y:= maxy div 2
loop
drawfilloval (x,y ,12,12,110)
drawfilloval (x,y,12,12,0)

x := x +1



end loop

Just check the surrounding block for changes in colour.

Math.Distance

Of course this will only give you the distance between 2 points, so you might have to figure out checking of what points will be enough to give you a good answer.

[Panphobia]

Yes as Tony said you could do that or just do something like var distance: int
distance := (x+x1)^2-(y+y1)^2
and whenever this point is moving and the closer it gets or when it passes over you do a certain thing, I think this is what Tony was trying to show you with Math.Distance

That helped, but I need it to move in every direction now.



drawbox (120, 120, maxx - 120, maxy - 120, 1)
var x, y : int
x := maxx div 2
y := maxy div 2

loop
drawfilloval (x, y, 12, 12, 110)
delay (10)
drawfilloval (x, y, 12, 12, 0)

x := x + 1

y := y + 1
if x >= (maxx - 135) then
loop
x := x - 1
y := y + 1

drawfilloval (x, y, 12, 12, 110)
delay (10)
drawfilloval (x, y, 12, 12, 0)
if y >= (maxy - 135) then
loop
y := y - 1
x := x - 1

drawfilloval (x, y, 12, 12, 110)
delay (10)
drawfilloval (x, y, 12, 12, 0)

exit when y <= 135
exit when x <= 135
end loop
end if
exit when x <= 135
end loop



end if

if y >= (maxy - 135) then
loop
y := y - 1
x := x + 1

drawfilloval (x, y, 12, 12, 110)
delay (10)
drawfilloval (x, y, 12, 12, 0)

exit when y <= 135
if x <= (maxx - 135)then
loop
x := x - 1
y := y - 1
exit when y <= 135
exit when x <= 135
end loop
end if
end loop
end if
end loop

what exactly is the purpose of your program?

[AntoxicatedDevil78]

I'm trying to make the ball bounce, then make it bounce within the rectangle, then have it dodge an object in the rectangle

[Panphobia]

Ok so get the x,y coords for all 4 points and do something like this,

code:

if ballY >= yHighRect then    ballY-=1 if ballY <= yLowRect then    ballY+=1 if ballX >= xRightRect then    ballX-=1 if ballX <= xLeftRect then    ballX +=1

you could tweak this pseudocode to make it bounce all around, but that is the general way i was taught in grade 11, of course this is all in a loop, so it will keep going, that is for the bouncing, however, you could use this also to make it dodge it, you could make another if to see if they are occupying the same space, and then move the ball xy in a different direction
