I have this lamp object. And i marked with a red circle the part i want to cut and make as a different object. Only the yellow part i want to make it object. So i can later use it in the game is object and also as item.
This is the lamp inspector:
Create a prefab of the lamp object and export it as a unity package.
You can then import it in other project as Custom package.
Source : https://docs.unity3d.com/Manual/HOWTO-exportpackage.html
Depending on the type of the model u have (obj, fbx etc) u need to go to 3d Modelling software like Blender or Max to modify the model. There u would be able to do any change to model u would like to including diving in too and maybe changing of shapes! Once done u can import them back into unity and have two different objects!
Taking the model into max as suggested would be the right idea. You'll likely take it in as an FBX.
Once you seperate the lamp from the post you may want to affect it's pivot.
For MAX look here
Be careful when exporting out the fbx again. I have noted that it seems to be best to export the model back out in metres. Automatic unit conversion may give unwanted results.

I am making a Multiplayer Game with MLAPI. The problem is, i have a ability system so every ability get executed over an ScritableObject. The problem is, if i have for example five Players in the scene all Players are referenced to the same ScritableObject. And so when somebody execute a ability. The other players are also doing it.
So my Question is can I duplicate my default ability ScritableObject so that every player has its own abilities ScritableObject but with the same Values as the default ability ScritableObject. I must do that over Script.
I know i could create a new ScritableObject and then make a method who paste my values. But maybe somebody has a better idea??????????
Afaik you can use Instantiate also for cloning ScriptableObject on runtime! Only you can of course not use any component taking more then the original parameter (which makes sense).
And the same way as ScriptableObject.CreateInstance this will of course not create an asset but only a runtime instance.
I tried to do this:
1) import file into blender (worked) -> it is the original file from apples vehicle example rc_car
2) exported it to .dae file (seemed to work, but unfortunately not in a way scenekit understands it properly)
(without any changes)
if i then start again the apple vehicle example, the car isn't visible and "invisible" hopping around
i did set global orientation to y_up and apply global orientation checked in blender when exporting.
what am i missing/making wrong?
p.s. what also is weird is that the dae file inside says:
Z_UP
although in export i defined y_up !?
I tried also other formats like obj, ply, alembic ...with the same result or nodes had other names than in the original.
This post: 56183036 is how I set the initial orientation and scale on my Turbo Squid models. It looks like you've already figured out that downloaded models don't always start with the rotation desired.
At the end there is a command line for setting Y-Up. Blender versions have changed since I did this, so I can't speak to y-up within Blender.
Models can be pretty finicky and some I've downloaded, just don't work after export. I found that trying a very simple model to make sure my math is working first, helps. A few times, my scale or color scheme was just way off and I didn't know it, couldn't see it, etc.
Hope that helps...
I'm new to AnyLogic and trying to figure out how Agent-based models should be set there. There is a famous Epidemic model, which I'm trying to reproduce. Most tutorials on classical ABM deal with old GUI settings.
For example, in version 8.5+, which is actual now, the Environment object (that was used for positioning of layouts) has been deprecated.
Now I see that new object Canvas is used to put the layout with agents on the page. But the structure of source code file is a bit unclear for me and I've failed to find relevant description how Canvas can be set for the purpose. (Besides I'm not sure that this is recommended way of doing this task.)
Question: I would love to learn the right way to arbitrary position the area with agents on the page. Below you may see what I get by default.
After some playing around, the 'minimalistic' functionality is as follows.
One should create some population with arbitrary name Person (population name people adds automatically).
The following structure of the Project is to be reproduced (arbitrary names are marked with yellow).
Comment: after adding a Canvas called mapCanvas one adds the function setCanvasCellColor with following body:
mapCanvas.fillCircle(person.getX(), person.getY(), 3, color);
It is clear that former two arguments stand for coordinates of a given point, then its size (i.e. 3) and color. Do not forget to add two arguments used in the body, namely, person as Person and color as Color.
From Entry Action of the statechart named state call the just made function. I've put black color here just for the sake of demonstration; chartreuse constant gets used instead in the Epidemic example.
main.setCanvasCellColor(this, black);
Finally, you may run the model to get the following picture.
Note
If one is reluctant to bother with Canvas, use Main - Presentation - xxx_presentation and click Draw agent with offset to this position checkbox.
I'm trying to Save/Serialize a GameObject and its components (with their current values), but I don't think it's possible, any ideas ???
Keep in mind that I don't wanna use an asset from the assets store, I wanna code it myself.
Thanks in advance :)
Sorry I dont have the rep to make a comment. I use two methods to acheive this save state.
First is what programmer seems to suggest, make a class that hosts the property's needed to recreate the object. Component names can be saved as strings, then fetched using
gameObject.AddComponent(Type.GetType(componentName));
If you are doing this alot it may be worth checking out this forum first.Here
You can serialize these classes using the unity serializer(the string names of types will serialise. You may have to make a sub class to handle the values in each object of different type.
This can be a fairly complicated approach so I prefer a file path serialized for a prefab in the resources folder. Any values that need saving can be saved in a serializable class like first approach which is referenced in a script on the saved prefab. This script has a method to apply all details saved in the deserialized class to the prefab when it is created. The details are captured by the script,added to the class and serialized whenever the object state should be recorded.
The exact way this is managed may vary but I have done this myself with he ability to store any values I could need. Even if you use a third party serializer from the asset store you will still have trouble saving entire objects, but you will be able to get enough info to recreate.
I've managed to save the components I want (custom scripts) by saving them in a json file, then serializing them with binary so they can be more secure.
Thanks to everyone who tried to help tho...
I am making a graphically simple 3D game in C++ using DirectX. The main problem I am having is with how to structure some things efficiently. Right now I know my goal for certain areas but not how to ideally perform them.
For instance, right now I am storing all meshes and textures in an Asset class with enumerated definitions pointing to each asset. All meshes and textures are loaded when the game starts by creating an Asset object and initializing it. From there I load meshes and textures to objects by assigning the pointer given by the Asset object. Is this the best way to go about this?
A harder topic is that of items. For the sake of argument I am going to say we are dealing with scenery. Right now my scenery needs the following:
A name
A mesh
Textures (optional)
Flags (such as Destructible, Flammable, etc.)
Status (such as Burning, Locked, Cursed, etc.)
Abilities (things the object actually does, such as becoming damaged when burning)
The first 5 things on this list are simply variables. But abilities are bothering me. The first 5 can all exist in one item class. But what I do not know how to do is somehow attach abilities to the object.
For example; I want the object to have the "Fire Nova" ability. At the start of each turn, the object damages anything near it.
For me, this means each object would need a "Trigger_Phase_TurnStart()" or some similarly named method and would then need a new "Fire Nova" class with its own unique action for that trigger and its own extra variables (Damage, Range, etc). So now I have the base object class and a new Fire Nova class that inherits from it.
But now what if I needed an object that has Fire Nova and Frost Nova and also Slowing Aura and other such abilities. Basically I need a way to add triggered effects to an object without needing a new object class for each of them.
So by the end I would be able to have say:
(pseudo code of the object's components)
name = Elemental Orb
mesh = "Mesh_Sphere"
textures[] = "Tex_Ice", "Tex_Fire"
flags = OF_Destructible
status = SF_Cursed | SF_Burning
abilities[] = Fire_Nova, Frost_Nova, Slowing_Aura
And this orb would simply be the object class with all these attributes. The object would then activate each stored ability's trigger at the appropriate turn phase for any actions to perform.
Right now I am thinking I might need to make a class for each ability possessing every turn-phase or action trigger (inherited from a base ability class) and have them perform the appropriate action when the object calls them from it's array of abilities. Would this be the best way to do this?
As a separate issue. Some flags would require additional variables that would otherwise be unnecessary. For example, Destructible would mean the object would have health whereas without the flag it wouldn't need it, or an Openable item would need an array of contents. What would be a good way to ration these variables to when they are needed? I do not need every wall to have health and an empty contents array for example.
Finally. Assuming the bullet-listed attributes above are all an item needs, how might you suggest I best store them? To clarify, I would like to be able to write:
CreateItem(ITEM_CHAIR);
and have this return the created object with name, mesh, textures, flags, status and abilities. What structure might be suitable for achieving such an end effect?
To summarise:
Does my current Asset storage seem feasible?
What is the best way to create abilities to attach to the object class without making numerous separate object classes?
Is there a way to limit the variables (or at least memory usage) when the associated flag is not present?
What structure or format would be best for storing fixed item definitions?
Sorry if this is a little long winded. If you cannot answer all the questions then an answer to one would still be appreciated. Question two is probably the largest priority for me right now.
Thanks for your time :)
I want only answer question 2 and it looks like you need a decorator pattern. In OOP a decorator pattern is useful when you have many ingredients and wants to decorate an object, for example a pizza. Unfortunately you need to create for each ingredient a separate class hence I think you have the right approach. The good thing is that with the decorator pattern you can wrap the object over and over with abilites classes and call only one method at the end to do all the stuff.
