I've got a model of a car imported into Unity. It's got multiple parts, and these have been organized into a hierarchy in the project explorer window.
I want to be able to "explode" the model - move each part outwards, so that each individual part can be seen.
Do you know how I can do this in one script? So far, I can use a translate function call to move individual parts, and I've had to make separate scripts for each part.
Any guidance on how I could do this would be great.
i dont know what you really want to do. if you want to make an car exlosion that you want to do it with a simple code you can use addForce function. it receives a paramter as a direction. you can use this code to throw parts of your car to diffrent directions and trigger the code in some event, but if you want something cinematic and controlled you should just start animating.

I'm making an isometric city builder using Monogame Extended and Tiled. I've got everything set-up and now i need to somehow access the specific tiles so i can change them at runtime as the user clicks on a tile to build an object. The problem is, i can't seem to find a "map.GetLayer("Layername").GetTile(x,y) or .SetTile(x,y) function or something similar.
Now what i can do is edit the xml(.tmx) file which has a matrix in it that represents the map and it's drawn tiles. The problem with this is that i need to build the map in the content pipeline again after editing for the changes to be displayed. I can't really build at runtime or can i?
Thanks in advance!
Something like this will get you part way there.
var tileLayer = map.GetLayer<TiledMapTileLayer>("layername");
TiledMapTile tile;
if(tileLayer.TryGetTile(x, y, out tile))
{
// do something with tile
}
However, there's only a limited amount of things you can actually do with the tile once you've got it from the map.
There's no such thing as a SetTile method because changing tile data at runtime is not currently supported. This is a limitation of the renderer, which has been optimized for rendering very large maps by building static geometry that can't be changed once it's loaded into the graphics card.
There has been some discussion about building another renderer that would handle dynamic map changes but at this stage nothing like that has been implemented in the library. You could always have a go at implementing a simple renderer yourself, a really basic one is not as hard as you might think.
An alternative approach to dealing with this kind of problem might be to pre-process the map data before giving it to the renderer. The idea would be to effectively separate the layers of the map that are static from those that are dynamic and render the dynamic tiles as normal sprites. Just a thought, I'm not sure about the details of how this might work.
I plan to eventually revisit the Tiled API in the next major version of MonoGame.Extended. Don't hold your breath, these things can take a lot of time, but I am paying attention to the feedback and kinds of problems people are experiencing with the existing API.
Since the map data is stored in a XML (or csv) file which runs through the Content Pipeline you can not change it at runtime.
Anyways, in a city builder you usually do not change existing tiles but you place object on top of existing tiles.
Does anyone know of macro or custom command I can make to quickly annotate the area of a polyline in autocad?
I'm doing a project where I need to measure the lot and house size of several city blocks. I've got a drawing going but I don't want to measure and write out the area of each site, that will take to long. I've seen custom commands in the past that quickly do this kind of thing but I don't know how to make my own.
And I'm desperately avoiding doing it by hand one at a time as most likely I will need to make adjustments to my design later on.
The best method I can think of is to utilize the MTEXT command and use a FIELD to link the Area of the Polyline to the MTEXT box.
Type FIELD at the command line, choose Object, select your Polyline and you will see the Area property.
Here is a link on the CADTutor site that covers it a bit more in depth along with a link to a forum post that has this automated via a Lisp routine.

I have a VTK data file for a 3D model and I am trying to show a transformation applied to it.
I have the point coordinates/polygon data for every state in the transformation (there should be about 10-30 states), i.e. I could write another VTK file for each step.
I am trying to create a nice animation where each state would be shown for say, 1 second and then switch to the next one, as fluently as possible.
What would be the best thing to do?
There are a handful of ways to animate something in VTK, with examples on the VTK Wiki.
The easiest way is probably to subclass vtkCommand (DataAnimationSubclass), but the "VTK/right" way is with vtkAnimationScene (AnimationScene).
I have a requirement where in I have to move four objects on an elliptical path.
Am using Expression Blend and was able to create a motion path quite very easily and place objects over it. It was also cool creating storyboards and keyframes.
The problem came when i wanted all the objects to move at once, their starting points being different. I mean I want the sarting point of each object to be different.
I have searched for answers but could find people ending up in creating their own custom paths through code behind.
Is there a way that we could achieve this through Expression Blend?
Thanks in advance,
Sri
What are you trying to do, exactly? If you are creating a Storyboard, why not just give each object a different starting location? If you are trying to create a Carousel or something like that, check out PathListBox. If neither of these are helpful, post some more specifics.
I have to write a multiplayer pacman game in Java for a university assignment and I'm after some feedback for my design so far.
So I'm trying to go down an MVC style and this is what I've sketched out.
I've never designed anything using MVC, so my knowledge is really only from the pragmatic programmer and a short lecture so it's quite possible I'll have misunderstood or misinterpreted it slightly.
Also, most of the tutorials I've seen for designing simple games don't mention MVC at all so is this a case where MVC is not a good pattern to use?
My idea so far is that the Game State class would be the main source of data storage as it were, and would use a 2d array to store the state of the game, where the ghosts are, where pacman is etc.
The Game class would be the main controller class that would contain the main game loop and control all the interactions between the data (game state) and the view (probably a GUI representation - I just added text based really as an example).
After I've got the game working I'm going to have to split it out into client/server. It seems to me, by using this model, that it wouldn't be too hard to keep most of the the data and processing on the server and have the clients interact with the controller and draw their own views. I have no idea (yet) how this may effect the performance of the game over a network so I'll have to research into that further once the single player version is done.
Any tips or advice, based on my design so far, would be greatly appreciated - also bearing in mind that it will eventually have to be a multiplayer game.
Cheers,
Adam
On the contrary: MVC is actually a very good thing to use for this type of problem and the Swing framework does a really nice job at supporting it.
You should probably first read up on MVC. Just as an overview, you will be trying to separate how the game is represented internally (the model), from how it is drawn (the view) and how that state is to change (the controller).
First think about everything you need to model the current state of the game. Having an Entity that defines some basic behavior and subclassing it for the PacMan and Ghost like you do is probably a good way to start, but you'll probably want to call your Map a GameBoard or the like (giving things the same name as library classes is generally a bad idea: you don't want to confuse it with java.util.Map). To wrap up the model section, you probably want to wrap them all up in one class who 'knows' the entire state of your game. Since this is your GameState class, you probably want to redraw your arrows.
Since determining the view is likely to be fairly easy, you can go there. You can give your GameState a draw(Graphics) method and invoke this from whatever your view is (which you'll decide later). This might in turn delegate do each of your Entities, who might in turn delegate it to a Sprite or Image object that they have. Now your view, who's likely to be a JPanel or the like, can just call draw() using its own Graphics object from within its paintComponent() method.
Now you still need a controller to actually make stuff happen. This is likely to be some object with a KeyListener hooked into the view as well as an InputStream and an OutputStream to handle communication with the other player (it probably also needs to be the one to worry about synchronizing the game state). It also needs to also have a timer so that it can tell the units to update periodically. You do need to decide who makes the decisions on whether the moves are legal: the controller could do it, the GameState could, or it could just give the Entities the information they need and let them do it themselves.
Once you have all of these parts, you can wrap them up in one final class who knows everything and gets it all set up and such. There's a lot more that I'm glossing over and several more decisions that you have to make, but it should get you going.
I agree with James entirely, and would like to add that you might also want to make sure that this 2d array of yours for the game state can handle some edge cases like multiple ghosts occupying a tile, a pacman and ghost in the same tile (depending on how you handle it in your code), the pacman's food dots, etc.
Good planning more often than not makes the best programs, I'm glad to see you have started off with a diagram.
