Hey all,I'm making a space invaders type clone and just need to sort out the scoring for it to be finished.I can't work out how to do coz I do this.

and nothing is printed to the screen.If the print command is outside the loop it prints score 0 but dosn't +10 for every sprte hit.
Anyone know what I can do.Thanks.

I think it may have something to do with where you place your text, but could you just throw all the code in there? I'll check back on this thread.

Hmmm... Maybe if the score was at the start of the loop? Can't test it cuz I dont have the pic files but it should work then.

It's proberly this
ink rgb(10,10,10),1
rgb(10,10,10) is nearly black so the text won't show up.
if you want white text use
ink rgb(255,255,255),rgb(0,0,0)

Also you don't want to be using the ink command every loop if you don't have to, just use it before the loop if you are going to be justing the same colour all the time.

If you are using dbpro right click in the editor and click rgb colour picker and it will insert the rgb statment for the colour you pick with the windows colour dialog.

It should show up because I'm using a blue background but I can only see it if the print command is outside the loop but if I do this it dosn't add 10 for every sprite hit.BTW i'm using DBC

you will have to dump the automatic sync and do it manualy to get it to work, at the start of the code put

sync on:sync rate 0

sync rate 0 is as fast as your PC can go, so you might want to change to 40 or something, then after the score is printed do a sync

print "score",score
sync

sync tells the system to show all the changes that have been made to the screen since the last change, you can do all sorts of stuff before the sync, move objects, animate them etc, but you won`t see anything happen until you do a sync, so you bneed a sync at the end of your program loop.
the reasons you need to do the manual sync rather than just let DB handle it are twofold, first...your code will run MUCH faster, and second....DB does not handle things smoothly on automatic anyway, and you don`t get things like text displayed properly.
You might also like to consider using text as the command to show your scores, It`s more flexible and faster than print, you would mod the code to read

text 0,0,"Score:-"+str$(score)

and by altering the x and y values you can move the text around the screen easily, also use the text commands to chang from the standard system font to something better and rescale it to make it more visible, etc, cheers.

You almost got it.

You only need one sync at the end of your game loop.

1. Move the SYNC after the DO command to before the LOOP command.
2. Remove the SYNC in your print routine.

I tested your code in DBP and that worked for me.

3. Cosmetic change: add a space after the word 'score' to make it look nicer. The STR$() function does not add a leading space.

Well, it works for me in DBP.

Since I don't have DBC, I can't offer any more advice.

Have you tried putting the sync rate 0 on a different line than sync on.
I'm only a learn but it might work.
I think that the colon inbetween the to commands is a DBPro feature.
P.S. I'm making a space invader clone aswell.

You usually dont want to have SYNC RATE 0, as that will let the program run as fast as the computer will allow, which will get out of control on higher end comps.

Sync ON : Sync rate 50

Is usually good, maybe 60

what screen mode are you in???, make sure you are not in 16bit, I know it has issues in classic with the way the screen is drawn and coloured, start the code with the line

set display mode 640,480,32

if that fails then your gfx card is prolly a 3DFX card, they DO have problems with DB (both DB Pro and Classic incarnations), also make sure you have the latest driver for your GFX card and dx 8.1 installed for classic or dx9.0b for pro, also make sure you have the last upgrade for classic (available off the DB classic section of this site...move the mouse to the top of the page and select darkbasic from the dropdown under game development and navigate to the classic patch) other than that...it SHOULD work, if it doesn`t then it`s an issue with either your GFX card or the directx setup, (onboard graphics chips from won-mo-ting Fx can be a problem too )

Hi Proshooter

I have been watching your problem and it seems that no one has been able to help you. I am a newbie at this as well but I have DBPro. So I can't test what I am saying.

I have read in a book somewhere that DBC does not support global variables and the only way to use your variable(s) throughout your code is to make your variables arrays.

i.e. dim score(1) the 1 referring to the number of elements.

Then refer to score as score(0) 0 being the first element

So score = score+10 would be score(0) = score(0)+10

Then as mentioned before you could put

text 10,10,str$(score(0))

either in a function or gosub (a function would be better) or in the main body of your loop.

This might not help but is worth a try

I can't see in your code anything to set the colour of your text, try putting ink rgb(255,255,255),rgb(0,128,255)

this would set the text colour to white and the background color to what you have now.

good luck
Mickeyfyn
