Addressing another type within same type
Blitz3D Forums/Blitz3D Programming/Addressing another type within same type

| I have a type called .player . As players log in it creates a new.player . I have a main loop that checks each players moves/actions in turn. My problem is , if i want to address a different player than the one the loop is on, say to change a field value , how would i access that player and then continue with the main loop? my only solution i have come up with so far, is to save players stats to the HD, and then i can access them randomly by player\name. the down side is this takes time accessing the HD. The upside is i have random access to any player field. |

| The what-what? You can have more than one variable of the type defined. Or am I not understanding you right? Example: SeedRnd 143 Type player Field name$ End Type players.player = New player players\name = "Luke" players.player = New player players\name = "Joe" players.player = New player players\name = "William" players.player = New player players\name = "Jack" players.player = New player players\name = "Averell" For players.player = Each player For otherplayers.player = Each player If Rand(1, 4) = 1 Then Exit End If Next Print players\name + " vs " + otherplayers\name Next While Not KeyDown(1) Wend |

| What i wanted was a way to access directly, another player, and not have to search through the type to find it. time needs to be kept to a minimum, as there could be many players in the loop |

| Hard disc operations are going to be slower than searching a fairly substantial list. How are you getting a situation where you know the name of the player you want but you don't have their type handle? We need an example. |

| I get the player name from his EntityName Lets say there are 1000 players the loop is on player 56 , who targets player 990 I read player 990`s name from his Entity Name. would it be faster to loop through ALL players upto 990 to get his data , or just read from HD. remember this would be a process I have to do every loop for many of the players logged in |

| OK i done some testing running a type with 10,000 players and searching for player 9999 takes from 4 to 9 millisecs to complete a search for a Int ,and 19 to 37 millisecs for a string search ,on my machine (not compiled). As this is way more players then the game will ever hold, I agree that a search through a type is the best way to go. I just wish there was a way to directly access a type without searching . for example: TypePointer = (player\name$="john") - pointer stops at first matching type :) |
| ||
| the loop is on player 56 , who targets player 990 You should have a 'target.Player' field that points to the current target type instance Type Player Field x#,y# Field Target.Player Field Health .. End Type .. For thisPlayer.Player = each Player If thisPlayer.Target\health < 5 ...whatever Next did I understand you correctly? |

Not 100% sure what your trying to do but you could probably make use of the old favourite - store the handle to the type instance in the entity name like so ...type Mytype field Name$ field Entity field Health field Etc.. end type m.mytype = new mytype m\Name = "Stevie G" m\Entity = createsphere() m\Health = 100 Nameentity m\Entity, handle( m ) To access directly based on the Target Entity .. Test.mytype = object.mytype( entityname( TargetEntity ) ) Test\Health = Test\Health - 1 Another alternative would be to define an array of types .. type MyType field name$ end type dim MyTypes.MyType( 100 ) MyType(0 ) = new Mytype MyType(0)\Name = "Joe Schmo" So to access player 990 it would be ... HisName$ = MyType( 990 )\Name Stevie |

| if someone leaves the game, then player 990 could become player 989 in the type list. I think i will have to search every loop also the target and/or player stats can change from loop to loop, so i do need to read them every loop. |

| "Not 100% sure what your trying to do but you could probably make use of the old favourite - store the handle to the type instance in the entity name like so ... Bingo! There's your answer right there, pay attention to this man :) |

I think I know what you mean, here's my take on it:type npc_dat field x, y, z field target.npc_dat end type ; Create player NPC player.npc_dat = new npc_dat ; Create 10 NPC's for n=0 to 9 npc.npc_dat = new npc_dat next ; Makes the field 'target' point to the last 'NPC' player\target.npc_dat = last npc_dat ; Delete the current player delete player ; Point player.npc_dat to the last npc_dat player.npc_dat = last npc_dat You have to remember that when you declare a type, all you are doing is starting a list of 'npc_dat's. When you create a 'new npc_dat', you're just simply adding to that list. Imagine you're drawing a list out on paper and you have your red pen (your 'player.npc_dat' variable) lined up against the first item. The black pen is lined up against the first item as well - this represents the 'npc.npc_dat' variable. The pens can point to any one of the items in the 'npc_dat' list by either looping through them, or declaring another variable (aka using another pen to point with). All you are doing when you declare a 'randomvariablename.npc_dat' is creating a pointer to that list item. You can create pointers within types to other items in the list as well. |
