This replaces the current Processmovement subroutines to have an extra "catch-all" code to make sure people don't wonder off a tile completely, which is what causes the flight effect where sprites start running off-screen. It's copy and paste, I can't be arsed with decent formatting, so here you go. Processmovement: Code: Select Case GetPlayerDir(Index) Case DIR_UP Player(Index).YOffset = Player(Index).YOffset - MovementSpeed If Player(Index).YOffset <= 0 Then Player(Index).YOffset = 0 Case DIR_DOWN Player(Index).YOffset = Player(Index).YOffset + MovementSpeed If Player(Index).YOffset >= 0 Then Player(Index).YOffset = 0 Case DIR_LEFT Player(Index).XOffset = Player(Index).XOffset - MovementSpeed If Player(Index).XOffset <= 0 Then Player(Index).XOffset = 0 Case DIR_RIGHT Player(Index).XOffset = Player(Index).XOffset + MovementSpeed If Player(Index).XOffset >= 0 Then Player(Index).XOffset = 0 End Select Processnpcmovement: Code: Select Case MapNpc(MapNpcNum).Dir Case DIR_UP MapNpc(MapNpcNum).YOffset = MapNpc(MapNpcNum).YOffset - WALK_SPEED If MapNpc(MapNpcNum).YOffset <= 0 Then MapNpc(MapNpcNum).YOffset = 0 Case DIR_DOWN MapNpc(MapNpcNum).YOffset = MapNpc(MapNpcNum).YOffset + WALK_SPEED If MapNpc(MapNpcNum).YOffset >= 0 Then MapNpc(MapNpcNum).YOffset = 0 Case DIR_LEFT MapNpc(MapNpcNum).XOffset = MapNpc(MapNpcNum).XOffset - WALK_SPEED If MapNpc(MapNpcNum).XOffset <= 0 Then MapNpc(MapNpcNum).XOffset = 0 Case DIR_RIGHT MapNpc(MapNpcNum).XOffset = MapNpc(MapNpcNum).XOffset + WALK_SPEED If MapNpc(MapNpcNum).XOffset >= 0 Then MapNpc(MapNpcNum).XOffset = 0 End Select Enjoy. |

I mean I don't understand the flight effect and the sprites walking off the tile/screen? How would this code affect that? |

So it already happens without this code.... that's weird. |

DarkPhoenix wrote: So it already happens without this code.... that's weird. No, it's not. The reason the speeds can only be 1, 2, 4, 8, 16 or 32 is because the movement is pretty much just taking the speed value away from 32 until it reaches 0, or adding it to -32, depending on which direction you're going. Of course, if the number isn't a factor of 32, it wont reach 0 exactly, which causes it to never stop walking. This code simply makes sure that a number can never go over the maximum or under the minimum values. |

wait... there is more than two speed values that are usable? O_o |

so you can add more when you add this code, if I understand what you are saying. |

DarkPhoenix wrote: so you can add more when you add this code, if I understand what you are saying. This code would allow, say, higher speed for your character to make you move slightly faster than other players. Or for speed buffs and what not. So, if you have 4 walk speed by default and you have you get +1 from a buff or item, you'd have a walk speed of 5, allowing you to walk just a tad faster. However, with the default code, if you had 5 walking speed, you'd just glide off the screen and never stop moving. That's the problem. That's what this code fixes. Awesome tut, Robin. Very useful. |

on the old way it could be only 4 8 16 or 32 or else it will glide off with this it can be any number |

Very nice tut. I'll try to make it work with my server-side canmove sub xD Client side deciding the speed is just way too much insecure =/ |

Very good script there, and it looks as if you kept it very compact and with no trash script involved. Gotta give you some nice props for this one! |

Also wouldn't adding it server side cause more lag? After all it's not like you want to add a heavier load to the server when the client can do it, right? |

The client-side CanMove stuff is all there to counter-act the packet delay. It's not nice pressing "up" and only moving a second or so later. It's decent enough theory, but not programmed very well. Handling speed and movement server side is fine, but having it all handled client side for a player's own character only is perfect. As long as you do some checks to make sure it's not out of sync, which is a common problem in all Mirage-based engines/games. It's an easy fix, just like this was. I might post a tutorial to fix it, eventually. |

Can you fix that lag where other people's movements are a bit laggy? Or is just something I'm going to have to live with? |

| Post subject: | Re: [Feature] Run & Walk speed values. |
I haven't really seen anything to show whether that's a programming error. I've noticed lag where people host the servers themselves, but when I was hosting my own game on a VPS, there was no movement lag at all. |

It has to do with your ping. You could receive data every 200 milliseconds or 20 milliseconds or even 1000+ milliseconds (which means 1 second of delay). When the player moves you will receive their location every however many ping. They can move faster than your ping (unless you're under 32 or something probably) and when you catch up with the server they will jump from where you currently see them to where they actually are...which is what we call lag. |

I wouldnt expect to really lag on a 2D DX7 game. Idk though.
