I made a saving thing for my game but it keeps saying "runtime error 118..."
could anyone tell me what is wrong with my code

+ Code Snippet

_check:
if file exist("data\567_233.arr")=1
load array "data\567_233.arr",save()
charobj=save(0)
posx=save(1) : posy=save(2) : zone=save(3)
lives=save(4)
flees=save(5) : wins=save(6) : deaths=save(7) : overdrive=save(8)
else
dim save(9)
save(0)=1 : save(5)=0
save(1)=250 : save(6)=0
save(2)=-250 : save(7)=0
save(3)=4 : save(8)=0
save(4)=1 : save(9)=0
save array "data\567_233.arr",save()
undim save()
goto _check
endif

Here you go. Just needed to dim the array before you loaded it. Don't forget to undim when finished.

Using undim deletes the dimension array, thus freeing memory.

but if you use the array all the way through your program then DBPro will delete everything for you, so unless you need lots and lots of speed you do not have to undim or to delete objects. However, it is good prctice to do this as when moving on to bigger and better languages, because variables will remain in the memory until you tell your program to delete them or until the computer is turned off.

Part of solving the problem is actually noticing that the problem is there in the first place

Thanks for the help. Does anyone have a realistic jumping code?

If you have a defined type like...

+ Code Snippet

type tbad
      name$ as string
      mass# as float
      speed# as float
      life# as float
   endtype

And you apply it to an array like...

+ Code Snippet

badcrew1(0).name$="Leader: Crow Hawk"
badcrew1(0).mass#=500

then does that infomation get saved when you save the array?

Maybe. Your best bet is to just try in this case.

Also, I don't think you need the symbols in an array ($,# etc). Could be wrong.

No, the compiler won't let you save an array based on a UDT. You'd need to write the load/save functions yourself.

Quote: "Could be wrong."

Nope, you're perfectly right. If you use the 'as xxxx' way of defining a variable, then you don't need the extra symbols such as # or $.
