actually, the code works as-is. it's doing what it's supposed to. the problem is that after a restart, it goes back to his/her "Num:" label, prints the prompt and then somehow hides the text. it's still there but you can't see it.

that's not the problem. num is being set to a new value after the restart/re-prompt (or set to the same value if you press <enter> during the "target score" input routine). but, you're on the right track. there is no re-set of the players' scores upon restart. add the following lines under one of the many labels that are utilized during a restart:


(not sure why you're using Reals to define Integer scores, tho)


couple things to offer here, revonneer, which may rectify the problem:

1) to put it bluntly, the code is spaghetti. it's bouncing all over the place with multiple and unnecesary Goto statements. best practice is to avoid "Goto" when possible. it will help situations just like this, when you're trying to narrow down a glitch. group relevant code together. use indents to help keep your code visually tidy. use blank spaces between the various snipets of code to separate groups of instructions that are related to one another. you are using REM statements nicely, though, which helps you keep track of things, but getting into a better practice of keeping your code clean will make your programming experience less frustrating as you delve into more and more complex works.

2) SYNC RATE and SYNC ON:

these pieces of code:







start your code with SYNC ON and SYNC RATE ## and you never have to use them again. later in your code, just use a SYNC when you want the screen to refresh. there's really no need to change the sync rates during the game you've written. over-use can and will cause problems, and i'm thinking it's why the bug exists, but the afformentioned 'spaghetti' code is requiring more time for me to follow than i'm willing to offer right now in tracking down the bug.

meanwhile, your code works with only a slight hitch, and i commend you for that. i'm new to DBPro (since mid-December '05) and i enjoy browsing the 'Newcomers' threads, using other Newcomer problems as exercises. it's helped a great deal and i suggest that other Newcomers do the same.

EDIT - one (possibly important) item i forgot to mention:

this:



the more-experienced coders here regularly suggest avoiding DELETE OBJECT when possible. it causes unwarranted lag issues and can cause some bugs to pop up, etc. in your game there's really no need to delete them and re-create them for each round. a work around might be called for where you create the objects once and then HIDE OBJECT when you don't want them on the screen, using SHOW OBJECT when you do.

good luck

here you go....

i worked around the problem and used the entry buffer instead of the input command... same effect though.

it works fine now, next you could add some AI, if u haven't already ofcourse.
