[Oli2uok]

I need to make a few post to ps you, but what are you stuck with?????

Cant seem to get the changeFace to work. tried loads of diff ways!!

[Oli2uok]

[QUOTE=tinman;94730]what you stuck with[/QUOTE
Really stuck on this code, have done it loads of diff ways.

public int changeFace(int n);
{

if ((n >= 6) || (n <= 0))
{
OUDialog.alert("Argument to changeFace() message " + (n) +" is out of range");
}
else
{
return this.face(n);
}
}

if you post some specific questions others on here may be able to help.

public int changeFace(int n);
{

if ((n >= 6) || (n <= 0))
{
OUDialog.alert("Argument to changeFace() message " + (n) +" is out of range");
}
else
{
return this.face(n);
}
}

I sent you a PM with the approach I took.

I dont think it has come through!!

[kyussy]

yeah it's vanished somehow :(

never mind, I just said that I'd used nested ifs, it looks a bit messy but seems to work.
for the next bit I used a mixture of the reset() method and the right() method from the marionette project.

That bloody background square though....

Thank you, will have a look tomoz now, getting bored and tired.

OP here,

I'm not looking for answers here to questions just to guidance of wheather I'm on the right track or not. And that first post could be totally wrong!. I don't think the unit books properly prepared us for this question instead, I understand things in the books but this question is difficult to me and with no one to help the java forums seems to be the best place to ask.

[kyussy]

hi mate,

Have you spoken with your tutor? If you're stuck on a question he can tell you which section of the books to look at.

Have you got the change background method working yet? I can't get that square to update:confused:

finished the rest though :)

I'd totally agree with that, I can see how the java concepts work in the book and the activities, but i struggle to apply them to the question without searching for help on place like this.

It doesn't help that I emailed my tutor asking for help last thursday and it took him 6 days to reply, so I now have 1 day left to finish the question!

OP, for ii) I have used the same idea as kyussy and used if - else -if statements for the possible values of n. I can't get it to work yet but i'm just going to hand it in as i need to move on to the next bit now. Next TMA i'm going to do each question as I finish the relevent chapter so i don't get into this situation again!

Kyussy, have you used update(), reset() in the background method? I'm just working on that now.

I was thinking if I used bg.setXpos(75) it would only work the first time the code was used, so can we say bg.setXpos(bg.getXpos + 75) or have I just made that up? lol

[kyussy]

call him and get an extension!

bg.setXpos(bg.getXpos + 75)

I used background rather than bg, it won't work for me with bg as it's not declared. I also have this. in there.

try if n<=1 && n <=6
if n== 1 etc
if etc...

else alert!

Thank you, i'll have another crack at that bit :)

Hi

any advice on how to assign the arguments to the instance variables in (i)

everytime i try to assign them just comes up with error messages

thanks

Without your code and your error messages, I'm afraid that we have little chance of being able to help you. Best of luck.

[owlsno1]

public Dice(Square bg, Circle tL, Circle tM, Circle tR, Circle mid, Circle bL, Circle bM, Circle bR)
{

this.background = bg;
this.topLeftSpot = tL;
this.topMiddleSpot = tM;
this.topRightSpot = tR;
this.middleSpot = mid;
this.bottomLeftSpot = bL;
this.bottomMiddleSpot = bM;
this.bottomRightSpot = bR;
this.reset();
this.length = 70;

[owlsno1]

the code comes with no errors but then i need to execute a statement
Square s = new Square(); which results in an error:
Semantic error: Cannot cast Circle to Square

[evant]

Looks like were all on the same, im stuck on the same as you owlsno1. I can get the code to compile, when i create a new square, its always the same size no matter what i change it too though. so not sure if its correct or not
