here's the functions.. ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; ;; Highscores Handling procs ;; ;; by Mike Tilley ;; ;; Sunset Kangaroo 2006 ;; ;; ;; IMPORTANT ALL SCORES ARE INTEGERS AND ALL NAMES ARE STRINGS ;; please see attached example of use ;; ;; Functions ;; ;; ************************************************************** ;; setupHighscores(file$) ;; sets up highscore file. ;; args: file$ is name of file ;; IMPORTANT please look at function and ammend the table as you need ;; ************************************************************** ;; ;; ************************************************************** ;; sortHighscores(player$,pscore) ;; sorts highscores into order. ;; args: player$ is player name, pscore is player score ;; ************************************************************** ;; ;; ************************************************************** ;; checkHighscores(pscore) ;; checks highscores to see if players score is worthy of entry ;; and returns true if it is or false if it isn't ;; args: pscore is the player score ;; used like this : ;; If checkHighscores(player_score)=True Then ;; do whatever - e.g. get players name ;; sortHighscores(player_name$,player_score) ;; End If ;; ************************************************************** ;; ;; ************************************************************** ;; deleteHighscores() ;; deletes all highscore types from memory ;; ************************************************************** ;; ;; ************************************************************** ;; saveHighscores(file$) ;; saves highscores to file. ;; args: file$ is name of file ;; ************************************************************** ;; ;; ************************************************************** ;; loadHighscores(file$) ;; loads highscores from file. ;; args: file$ is name of file ;; ************************************************************** ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; Const tablesize=10; 10 is size of table Change this to change size of table Type Highscore Field name$ Field score End Type ;; change number in brackets to have diffent size score table ;; must match size in setupHighscores Global hi.Highscore Dim highscores.Highscore(tablesize) ;; sets up highscore file. ;; args: file$ is name of file Function setupHighscores(file$) ;; if file doesn't exist then set up a new highscore table and file If Not FileType(file$)=1 Then fileout=WriteFile(file$) ;********************************************************** ;;put whatever scores and names you want in here ;;for larger or smaller tables add or remove pairs of lines ;; must have same number of entries as tablesize const above WriteString(fileout,"Mike1") WriteInt(fileout,10000) WriteString(fileout,"Mike2") WriteInt(fileout,8000) WriteString(fileout,"Mike3") WriteInt(fileout,7000) WriteString(fileout,"Mike4") WriteInt(fileout,6500) WriteString(fileout,"Mike5") WriteInt(fileout,6000) WriteString(fileout,"Mike6") WriteInt(fileout,5000) WriteString(fileout,"Mike7") WriteInt(fileout,3500) WriteString(fileout,"Mike8") WriteInt(fileout,3000) WriteString(fileout,"Mike9") WriteInt(fileout,2000) WriteString(fileout,"Mike10") WriteInt(fileout,1000) ;******************************************************* CloseFile(fileout) EndIf End Function ;; loads highscores from file. ;; args: file$ is name of file Function loadHighscores(file$) filein=ReadFile(file$) For a = 1 To tablesize hi.Highscore=New Highscore hi\name$=ReadString(filein) hi\score=ReadInt(filein) Next CloseFile(filein) End Function ;; saves highscores to file. ;; args: file$ is name of file Function saveHighscores(file$) fileout=OpenFile(file$) While num <tablesize For hi.Highscore=Each Highscore WriteString(fileout,hi\name$) WriteInt(fileout,hi\score) num=num+1 Next Wend CloseFile(fileout) deleteHighscores() End Function ;; sorts highscores into order. ;; args: player$ is player name, pscore is player score Function sortHighscores(player$,pscore) tempname$="" tempscore=0 For hi.Highscore=Each Highscore If pscore>=hi\score Then tempname$=hi\name$ tempscore=hi\score hi\name$=player$ hi\score=pscore player$=tempname$ pscore=tempscore End If Next End Function ;; checks highscores to see if players score is worthy of entry ;; and returns true if it is or false if it isn't ;; args: pscore is the player score ;; used like this : ;; If checkHighscores(player_score)=True Then ;; do whatever ;; sortHighscores(player_name$,player_score) ;; End If Function checkHighscores(pscore) yes=False For hi.Highscore=Each Highscore If pscore>=hi\score Then yes=True End If Next Return yes End Function ;; deletes all highscore types from memory Function deleteHighscores() Delete Each Highscore End Function --v and heres a quick example of their use.... Include "highscorefunctions.bb" Graphics 640,480,32,2 Const name$="Fred" ; name for testing Const score=5500 ; score for testing setupHighscores("Hightest.dat") loadHighscores("Hightest.dat") Print"set up table" Print For hi.Highscore=Each Highscore Print(hi\name$)+" "+(hi\score) Next If checkHighscores(score)=False Then Print Print("not changed") saveHighscores("Hightest.dat") End If If checkHighscores(score)=True Then Print Print("changed") sortHighscores(name$,score) saveHighscores("Hightest.dat") End If Print Print"new table" Print loadHighscores("Hightest.dat") For hi.Highscore=Each Highscore Print(hi\name$)+" "+(hi\score) Next Print Print"Press any key to exit" WaitKey() --v hope they help someone out. If you do end up using them in a game please give me a little credit - ta
