Help for Pacman eating dots. Have no idea to do it.

[Jynx101]

It's telling me that the variable has no value on the for loop:

%Drawing dots that pacman eat

var dotx : array 1 .. 290 of int
var doty : array 1 .. 290 of int

i forgot to add this. it goes at the bottom:

for i : 1 .. 290
drawfilloval (dotx (i), doty (i), 4, 4, white)
end for

for i : 1 .. 290
DotsEaten (i) := false
if DotsEaten (i) = false then
drawfilloval (dotx (i), doty (i), 4, 4, white)
elsif DotsEaten (i) = true then
exit
end if
end for

[Insectoid]

What do you think that error message might be trying to tell you?

[Jynx101]

Yeah, ik that it says variable has no value, but it doesn't say which variable. It usually highlights which variable has no value, but it highlights the whole drawfilloval statement.

[Insectoid]

What variables are in the drawfilloval statement?

[Jynx101]

dotx, doty, and i

[Insectoid]

No, the variables are dotx (i), doty (i), and i. This includes dotx (0), dotx (10), doty (50), etc.

Do you think it's possible that you simply forgot to initialize one of your dotx or doty variables? Maybe there's a typo and you typed dotx (17) instead of (18)?

[Jynx101]

Yeah, you're right. I didn't do several of my dots properly. Thanks.

Now inside the draw loop, we'll add an if statement:

if dotsEaten (i) == false then
draw.filloval (dotsX (I), dotsY (i), etc)
end if

Now you only need to figure out how to detect if a dot was eaten, and set that dot to true in the eaten array. It will then no longer be drawn.

[Jynx101]

Btw, when you said to do the if statement, in english this says that is none of the dots are eaten, to draw all of them, right?

[Insectoid]

That if statement goes inside a loop. It looks at each dot, asks 'has this been eaten yet?' and then draws or doesn't, depending on the answer.

So i did it using collision detection, but it isn't working...

for i : 1 .. 288
drawfilloval (dotx (i), doty (i), 2, 2, white)

DotsEaten (i) := false

if DotsEaten (i) = false then
drawfilloval (dotx (i), doty (i), 2, 2, white)
elsif DotsEaten (i) = true then
drawfilloval (dotx (i), doty (i), 3, 3, black)
end if

if whatdotcolor (x + r, y) = white or whatdotcolor (x + r, y + r) = white or whatdotcolor (x + r, y - r) = white then
DotsEaten (i) := true
end if

end for

You've got all the pieces, but they're all in the wrong spots. Tell me, does this make sense?

DotsEaten (i) := false
if DotsEaten (i) = false then

Think about that for a minute- what exactly is happening here?

You need to break that big loop up into several smaller loops.

oh right...i'm stupid...its already set at false drawing all the dots

[The one they call Greed]

You are making every dot false every time it is scanned. Move that into a different loop and that should fix everything
