(39) Rama's Extra Blueprint Nodes for You as a Plugin, No C++ Required!

Hi Rama,
i love your plugin library. It is possible to make a “get light brightness” node to detect the light levels on pawn or other actor? I found here the code.

Hey there Ulrich,

I made one quick example for you in Blueprints (I converted the code you provided). So till Rama makes one you can play around with this. :slight_smile:

Hope you enjoy :slight_smile:

Many thanks ryanjon!!! :o

Yes thanks Ryan for doing that!

Great to hear from you Ulrich!

If I get time I will try to implement your request!

Thanks for all your own community contributions Ulrich!

Waoooo ! I love you Rama :rolleyes:
I am looking for a bundle like that since a long time !
It’s wonderful to share your work =)
I have not yet test all your library, but i have already a request :smiley:

I’m interest to have a node to control the object mass.
As you can see in my answer in this thread : Change Mass using Blueprints

##############
Here’s what I know :
We want to have an object with a Mass exactly = 1.00000 Kg
I take a mesh and set Physical properties :

  • Simulate Physics = true
  • Enable Gravity = false (we are in empty space)
  • Linear damping = 0.0
    —> at this step, my object has a Mass in Kg = 2198.014 :frowning:
    If i understand well, the Mass is calculated automatically depending on my shape mesh. Ok, so i will try to simulate a point with no shape in my calculation. To do that i use a Physical Material for my mesh :
  • Density = 1.0 (g/m3 = water density for example → it’s the default value)
    —> at this step, my object has a Mass in Kg = 2198.014 (no change, perfect!)
    Now I know my density = 1.0 so the engine seems to know the volume of my object (i would like to get this optionaly !) because mass[Kg] = density[g/cm3] x volume[cm3]

All this calculation is so complicated, i just want to be able to set manually the mass of my object !!!
In fact, there is a value in the physical material which cause this problem and seems to be use by the engine for the calculation :

  • Raise Mass to Power = 0.75 by default
    If I set Raise Mass to Power = 0.0 —> my object has Mass in Kg = 1.001 :frowning: WHY !!! :confused:
    ##############

Do you know how engine calculate the mass object ? what values and calculations are used ? I would like understand if it’s possible!! :stuck_out_tongue:
Maybe you can overpass the engine calculation to be able to “Set Mass” precisely with a node ! and verify if the “Get mass” node -included in UE4- returns the same value…

Thanks a lot ! :wink:

Awesome progress ! I hope epic will fix that bug that we can’t pack games with plugins in the next version.

Super cool new nodes, yay!

Hee hee!

Hi there! Nice colors in your post! :slight_smile:

You shouldn’t be setting the mass directly, what I can do easily is give you a node to set the mass scale of any primitive component / static mesh / skeletal mesh.

By playing with the mass scale on a per-object basis you can get the object to have the effective movement/physics that you want in game.

If you are doing some kind of 3d weight scale game and you actually need 1 kg every time, it will require much more effort on my part :slight_smile:

Mass scale is easy and universally useful!


**Mass to Power 0 = 1**

In fact, there is a value in the physical material which cause this problem and seems to be use by the engine for the calculation :
- Raise Mass to Power = 0.75 by default
If I set Raise Mass to Power = 0.0   --->   my object has Mass in Kg = 1.001 :(  WHY !!!! :confused:[/COLOR]

**If you raise anything to the power of 0, the value is 1! **

**Conceptual proof:**

This is because power implies Self-Multiplication, (x^2 = x * x), and the only thing you can multiply any number by and get itself  is 1.  So 1 is this Eternal Constant when it comes to exponential math, anything to 0 power is the same, constant, unchanged Origin of all exponential math. All numbers to the 0 power trace back to the same single point, the number 1, so this is Origin. And 0 represent the concept of Origin!


**Conventional Proof:**


```


                 X^y
 x^0 = x^(y-y) = --- = 1
                 x^y    


```




**So um, is that all you need then? A phys mat with power to 0?**


Mass scale as a BP node would be much more useful to more people and gives you fine tuned control on a per-object basis, and does not require phys-mats to be set anywhere :)

Rama what do you mean “Now work in packed games” ? What does it take to work in a pack game ? Is it possible to pack a game with all of the nodes from the plugin ?

Do I need a 4.7 to get it to work with packed games? Great work btw, everytime I open this thread, I find nodes I never knew I couldn’t live without :slight_smile:

I’m having some problems with Get Rendered Actors and Get Not Rendered Actors. If an actor is rendered once, then it will always be considered rendered, even off screen.

I have it so when I press F, it stores an array with the rendered actors, it also clears the old array if used again. I then have it print the name of it on screen. So I start the game and when I press F it prints nothing, after I look at the actor it prints that actor’s name, but if I look away it still prints that actor. The problem is also in Not Rendered Actors, I start the game and it prints the actor’s name, I look at it and it prints nothing, then I look away and still prints nothing. I’ve been using the default 0.01 seconds to check for rendered actors, but it seems to ignore that since it’s always considered rendered even with 0 seconds. Am I just not using this correctly?

Hey Rama, a quick question. Is the code included in the download completely free to use for any and all purposes? I don’t believe it contains any document that describes permissions as to what it’s allowed to be used for? And yes, I realize touching the code is not strictly necessary, but in some cases I would prefer to just use the C++ code directly instead of the blueprints.

As of 4.6.1, a code-based project is required to package the game, but a BP-only project can use the plugin during development.

This is going to be fixed by Epic soon :slight_smile:

Hee hee! Glad you like my various BP node offerings!

I will have to look into that, I am just using Epic’s function internally, so perhaps there is something going on with the function itself, send me a PM if I haven’t gotten to this within 2 weeks or so.

Yes the code is free to use anywhere you want!

I only request that you mention me in the credits for your game in the way that feels most appropriate to you, thereby honoring my contributions.

I prefer to be mentioned as simply “Rama”

:slight_smile:

Rama

Thanks, good to know this is possible at all at the moment, i guess i will just wait for 4.7 and in the meanwhile release game footage videos when there are new stuff to show off.

Yea! Epic has been telling me that getting plugins working in BP only packaged games is very high priority for them :slight_smile:
