Epic, Hire already, (before he is snap by rival company) !
Anyway, I have download & try some of the nodes. Thanks.
However, a question, do the
~ Change Hue
~ Change Saturation
suppose to work in the Material editior. I cannot seems to pull out these nodes.
Awesome thanks. I can’t wait to see your marketplace store.
I thought that too but wasn’t really sure.
I’ll use the binary save - didn’t even think of that 
Good idea.
Haha no rival company is getting me!
UE4 for me for always!
These nodes are for Texture2D, not for the material editor 
They are also not very efficient, you’re better off making a material and spawning a Dynamic Material Instance instead
Two New Nodes As Of 7/28/14
**Set Frame Rate
Set Frame Rate To Be Unbound!**
These two nodes can be run at any during game!
Can be part of your options menu or for testing how game behaves at low frame rates, or what the frame rate possible is with only your hardware limits!
Enjoy!
UMG Tutorial
I just posted my very first UMG tutorial, and the very first wiki about UMG in the Tutorials section!
As Mentioned in Hourence’s Twitch Stream
is the same node you could see in the Epic twitch stream with Hourences just last week!
I told Hourences I could give him the real system and he did wonders with it!
Get Current Operating System
annnnd
Get Milliseconds/Seconds/Minutes/Hours Passed Since Previous Recorded!
These two nodes can be used to
obtain the current local Operating System for your computer.
obtain the amount of milliseconds/seconds/minutes/hours that have passed since the you recorded for the first node! You can stores as many times as you want! They are simply stored as a string!
You can use these two nodes to record down to the sub-millisecond the amount of passing between game events!
**The milliseconds portion is a float, so you can record far smaller than 1 millisecond!
**
In the attached picture I record the amount of real-world between two key presses
Enjoy!
4 Array Analysis Nodes
** of Float Array

Min of Float Array
Min of Int Array**
Returns the /min value as well as the index in the array of that value!
See pic!
Enjoy!
[FONT=Comic Sans MS]Featured BP Nodes
**
Trace Data**
I’ve designed several BP nodes to make doing traces easier!
Again you can download and use these nodes as a plugin, even in non-C++ project!
Get Trace Data From Skeletal Mesh Socket
Taking Simple BP Node Requests
Anyone have a simple thing they’d like to have added to Blueprints?
What about more array manipulating nodes?
New Node as of 9/25/14
[COLOR=“#0000FF”]Draw Thick Circle With Axis Control[/COLOR]
New node for you!
With node you can draw circles!
And you can control their thickness, as well as how many points make up the circle!
You can also have axis control!
So you can draw circles horizontally, vertically, at angles, any way you like, with convenient BP node inputs!
See pics!
I don’t think I can use yet but that draw circle system looks awesome!
Does work on Mac? If it does it looks like a dream come true.
Also, is there a clear list of the available nodes included in it with a brief description? I know there’s a lot of that here but it’s kinda hard to scroll through on multiple pages.
**Mac**
Yes! The draw circle will work on Mac!
UE4 has its own platform-agnostic rendering system and my Draw Circle BP node uses system.
's BP List
Install my plugin (it’s free) and right click in any blueprint and type into the search filter “Victory”
Make sure you dont have a pin selected/dragged from, just regular right click, context sensitivity shouldn’t matter.
I put my nodes under one category heading so they are easy to find
**50-60 BP Nodes For You**
I can't actually write out the whole list here in thread though cause there's 50-60+ of them now :) (I've lost count)Hello ,
I may have something for your consideration.
Firstly, I was using your get Viewport Center & Set Mouse Position BP nodes to force the mouse cursor to center to screen (to be same location as the First person camera crosshair).
The reason I did that was so I can use the
-Enable Click events
-Enable Mouse Over Events
in first person view.
They worked fine, & you can highlight & pick objects like you are in the editor or the poker game using the first person camera view. Since the mouse is set the same location as my crosshaor, it appears that I am interacting with objects with the cross hair, but actually using the mouse (which is of course hidden).
However, I met with a major (while will surely be an in a release game), is that the mouse stayed locked to the center of viewport, even when you alt-tab to other applications! I can set a bool or condition unlock it on certain conditions (like pressing escape or exit), but I think in the end, its too risky in a released game, & I am scraping method of using using mouse over event to detecting item & picking up item in lie of sight, which is s shame as its trace very well, no matter if the is big or small.
I am now exploring the raytrace options of detecting objects in game. However, I thought it would really be useful if you can made a
-Enable Click events
-Enable Cursor Over Events
for the first/third person camera cursor. I think it will really be helpful for many people.
Solution Already Exists
I already have an easy solution for !
I have a node that lets you perform actions if the UE4 game is not the foreground window of the OS ! works in packaged games!
So you are setting the mouse cursor to be center of screen, you can use my node to stop doing that if the user tabs out / the ue4 game is not the foreground window any more
I have pictures of node here:
**Better Solution**
Why are you not just getting the center of the viewport and using the player controller deproject node to get the world space position of center of screen, and then tracing in the direction of the camera?
steps
1. get viewport center of screen
2. get player controller 0 -> get deprojected position (screen to world)
3. get the viewing rotation of the player's camera and trace in that direction
(rotation->As X Vector)
You can use my tracedata nodes to simplify the tracing process.
**then you dont need to set the mouse at !**
**Victory BP Node ~ Get Center of Viewport**
I already gave you a node in my most recent download (if you dont have it in your version of the Victory BP Library Plugin) to get the viewport center!
So just follow my 3 steps above and you are set, no mouse cursor involved, as long as it is the center of the screen you want
```
bool UVictoryBPFunctionLibrary::**Viewport__GetCenterOfViewport**(const APlayerController * ThePC, float & PosX, float & PosY)
{
```I am using the tracing solution now, so (mostly) is good. The node that let you perform actions if the UE4 game is not the foreground window of the OS will be useful in a package game. Thanks.
@, here’s another node that might be useful with the other texture related nodes.
It uses Zoid’s Dynamic Texture update method, and lets you pass in an array of FColors as the texture data.
I have it set here to do the whole texture at once because supposedly sub-regions don’t work, but I haven’t tested that yet. I’ve tested out the updating in general and it does work, though some of the streaming settings on the UTexture2D need to be set (so it may not work on UTexture2Ds that come out of the TextureFromDisk node, without a minor change there).
If sub-regions do work, it’d be really nice to change to pass in the region data (source X/Y, dest X/Y, basically).
If you ever figure out how to raycast and get a UV coordinate, would be the perfect second piece to allow for dynamic decals on skinned meshes (the update happens in the render thread, and is quite fast).
A new, community-hosted Unreal Engine Wiki - Announcements - Epic Developer Community Forums (UpdateTextureRegions is what you want)
/** Updates a UTexture2D* from an FColor array.
* Update texture from color data.
* @param ColorData Array of FColors to update texture with. Array is assumed to be the same dimensions as texture, otherwise call will fail.
* @param Texture Texture to update.
*/
UFUNCTION(BlueprintCallable, Category = "TextureFromDisk")
static void UpdateTextureFromColorData(TArray<FColor>& ColorData, UTexture2D* Texture);
And the definition:
void UTextureFromDiskFunctionLibrary::UpdateTextureFromColorData(TArray<FColor>& ColorData, UTexture2D* Texture)
{
// Sanity checks.
if (!Texture)
return;
if (ColorData.Num() <= 0)
return;
// Update region.
FUpdateTextureRegion2D *region = new FUpdateTextureRegion2D(0, 0, 0, 0, Texture->GetSurfaceWidth(), Texture->GetSurfaceHeight());
// Call the render command.
UpdateTextureRegions(Texture, 0, 1, region, Texture->GetSurfaceWidth() * 4, 4, (uint8*)ColorData.GetTypedData(), false);
}
Right now the way it’s set up it will leak the FUpdateTexture2D - so you may want to change UpdateTextureRegions to free the FUpdateTextureRegion2D but NOT the SrcData pointer, because that refers to your TArray of FColors, which you don’t want freed.
To fix that, change in UpdateTextureRegions
if (bFreeData)
{
FMemory::Free(RegionData->Regions);
FMemory::Free(RegionData->SrcData);
}
to :
if (bFreeData)
{
FMemory::Free(RegionData->Regions);
}
If you change , make sure to change the last parameter for UpdateTextureRegions to be true, so it will actually free the FUpdateTextureRegion2D.
