Frogger Game

[Jessica359]

Allo...again
I am making a frogger game as an end of year project. This is what I have so far and I need advice.

1. I don't know how to get the program to exit out when the green circle hits one of the boxes.
2. Does anyone have any suggestions on how to improve it or what would be cool to put in it or why are you doing this game its too easy lol i dunno anything

thanks

weird game...
first of all do you know how to use whatdotcolor function?
or do you know how to find the distance between two objects?
you could use the formula :distance = sqrt ((x2-x1)**2+(y2-y1)**2)
to find the distance between your circle and the boxes, but that would take too long assuming yu don't know arrays yet. Therefore I suggest using "whatdotcolor" eventhough it is inefficient way of doing it.
If you don't know how to use whatdotcolor then search for a tutorial, I think someone made one for it. Also I suggest learning about arrays.
Oh and make the boxes go the opposite way when they reach the end of the screen, or make new ones appear.

hey,

it might be a wierd game but its awesome

I researched whatdotcolor i put it into my program but it didn't do anything. Also we did learn about arrays and 2 dimensional arrays.
i'm just not sure were to start.

an array is very simple: instead of one variable representing one thing, an array variable represents as many as you put.
For example:
var number : array 1..10 of int
what that does is the variable number can now store 10 intergers in it and you select each one by having a subscript of number. For eaxample number (2) will give you the 2nd number.
You can specify the numbers by doing this:
var number : array 1..10 of int:=init (2,21,43,12,12,34,23,54,56,76)
So now if you say number (2) it will give you 21 scince that is the second number in your array that you specified.

ok ya we learned that but how is that suppose to help me get its to exit when it hits the cars?

[S_Grimm]

My best advice is to use something like this: (sorry, i can't really give specifics, had a hard time figuring out code)

code:

if (location of box1 = location of frog) or (location of box2 = location of frog) or ...........................  then put "You Got Run Over" end game else REST OF YOUR CODE end if

the location is the x,y co-ordinates

[Jessica359]

Awesome that makes much more sense!
Thanks for your help guys

[Jessica359]

Alright so another thing came up.
I took you idea of putting and if statement in.

code:

if x = boxx and y = boxy and x=boxy and y=boxx then cls put"GAME OVER" end if

But its not working?
My teacher told me something about keeping track of the x and y coordinates of the frog and boxes and something else about global declaration. Its just confusing

Any other sujestions on how to tell it to quit when it hits a box?

thnxs

[S_Grimm]

ok, what is your variable for Frog?

[Jessica359]

Its ok i got it to work by putting this in (the frog is x,y)

code:

if x >= boxx and x <= boxx +80 and y >= boxy and y <= boxy +80 then         cls         put "GAME OVER"

So now when it his teh white box it clears teh background and says game over but as soon as the box is pass the frog the game keeps going.

Change the cls to an exit

Turing:

if x >= boxx and x <= boxx + 80 and y >= boxy and y <= boxy + 80 then      exit end if

[Jessica359]

ya i thought of that except its not in a loop and when i put a loop in it messed up and doesn't even work.

[Sean]

Your game should be in a loop, so you have constant movement of the picture.

[petree08]

add this to keep your cars going

(mind this is genaric and not specific to your code)

if (CarX +CarLength ) < 1 then
CarX := maxx
elsif ( CarX -CarLength )> maxx then
CarX :=1
end if

[Asherel]

As Sean mentioned, your game should always be in a loop to allow continuous movement of your character, which happens to be Frogger.

There are ways to do it without loops, however since you're the one moving Frogger, you would have Input.KeyDown in your code.

Input.KeyDown allows you to manoeuver around the screen, if it is in a loop you can do this continuously until you meet a certain condition, or hit boundaries. Without the loop, one click and it stops completely.

When I have access to a computer that has my example program, I'll post it as an example. It has collision of dots, and then exits when the AI equals the Character.

So, to answer your question on how to exit it. Have a main program loop, and then when the condition of the two dots colliding is met, exit the program with the exit function.
