fantastic tutorial bro. ur a real one

Aw dang I thought you figured out a way to get the points of a target poly, very cool either way!

how would you make it transparent like darkwood instead of a flat color?

is there any way to fix all the ugly aliasing/bleeding?

Sounds promising!!

Wanted to comment about the last section as there is a potential bug here for those who might want to implement offset to the crosshair in case you want to move to another location other than the center. Before you call 'Deproject screen to world' the vector 2d that is passed, you need to add the offset vector 2d to it but you need to multiply the offset vector 2d with the viewport scale. If you do not multiply the offset with the viewport scale, your shots will not be accurate and will land outside your crosshair if you move it from the center point. The only time where multiplying by the scale is bad is when we are at the center, but that means that you are multiplying the scale with a zeroed vector 2d (the offset) which wouldn't have any impact. Hope this helps in case someone runs into this issue like me.

This video taught me a few new things about Unreal, its super awesome knowing I can draw on the screen instead of relying on textures as it allows me to do some cool things with some simple math.

Maybe it's just my computer... but it seems like the png attached to your tutorial is corrupted.

Help! I am getting gradle error: ERROR: cmd.exe failed with args /c "C:\Users\User\Documents\Unreal Projects\gaga\Intermediate/Android/APK\gradle ungradle.bat" :app:assembleDebug Running on 4.21 nvpack installed. Anybody has that error?

thanks, super useful video! <3

This is an amazing tutorial m8! :). I have a question, is there any way to activate the cone with an input? For example if you want the cone look like a flahslight. Thanks, you're a beast :D

holy cow ok yeah this could be massive helpful for my teams project idea

hey, that's a crazy good tutorial, thanks a lot!! I have a question though - how heavy is it on performance? can you still get 120 fps with those 80+ traces?

I know this is old, but its not hard to make a custom event that ends with a retriggerable delay and then have that event start on play to make your own timers and not use event tick.

Super great tutorial. I have a question. Is there a way to actually change the opacity of the mask so you can see parts of the background?

I'm absolutely losing my mind over this, the default brick-like texture works as it should, but as soon as I put anything into the texture object slot of world aligned texture, it refuses to pick up the updated character position. It's on my onTick event, it picks it up whenever I start the game, it just doesn't send an update every frame like it's supposed to.

The render target stuff reminds me of programming opengl with the array of triangles, telling it when its done rendering and beginning draw lol

How can I contact you? Do you have any professional email?

Amazing, thanks! I'm trying to change the opacity of the Material to have a semi-opaque effect, how do you achieve something like this? And potentially trying to blur the edges of the masks so it appears a bit softer. Thank you!

How would you approach the creation of the pivots in Blender? I tried To do it by projecting from view (bounds) but it doesn't seam to work in UE when imported

When I try to import any png or jpg file I get 2 errors: 1- "Unable to retrieve the payload from the source file" 2- "Texture has zero width or height" What's the issue? Edit: It was the size of the pic, changed it to 1024x1024 and it worked :}

I know how to make the cast ray longer but does Anyone Know how to make the vision cone larger?

Excelent

does this work on mobile?

SUUUPER useful loved it , and also there's another method by packing and setting pos to UVs and unpacking again , thnx a lot

Cool! Thank you!

Awesome tutorial, thanks! I managed to make it work with multiplayer thanks to your explanations in other comments. In general, it seems pretty heavy on performance, specifically if you want to draw it 360 degrees, and with 'only' 360 raycasts, it can look pretty jittery, is it expected? Any tips on if it can be optimized to make it more smooth / less heavy on performances?

I just discovered UV pivot baking and so your amazing tutorial, and it seems to be an amazing trick so I tried to reproduce it in Unity, but didn't end up with the same result :/ Each individual part seems to move in a weird direction (when applying the scaling part) and they also scale themselves, instead of just moving outward based of the (object pos - pivot pos) direction So if someone knows a solution for this...

How would I change this so that the end of the cone is centered on the mouse cursor? I know how to get the location of the mouse cursor and I can get it to draw a line from the actor to said location, but if I try incorporate the main bulk of your code here so that it generates a cone, it all acts very strangely.

Great tutorial. Was really nice to follow. What do I need to add that also niagare effects are only showing inside my line of sight?

Unreal Engine is a fantastic tool, BUT... some times very simple things dont work. For instance set a variable in an On Paint Override Function to a new value. The blueprint and the variable is not read only. The variable works on other Events very good , but not in "On Paint". Do you have a idea to solve this?

This guide was perfect for me. Not only did I learned a few new things about Unreal, but it also helped me with other tasks I had to do after the drawing. Some of which I was not even sure of how to search for. I should point out that it seems that the "Vector2D / float" boxes seem to not exist in Unreal 5. Using "Vector2D / Vector2D" with the same number in both X and Y worked though.

This is so awesome tutorial.

28:40 Ah yeah, looks like a Moire interference pattern.

Why not calculate the appropriate size of texture scale

why LERP??? Map Range Best

Hate to be the one to tell you this but this is a 2D widget, in world space. Notice how when you look at it from the side it's width is zero, that means it's 2D.

Hey there ! Great tutorial helped a lot ! But when i go on full screen the RenderTarget jumps to the left of the screen ( as its not in WorldSpace anymore) and when i move my camera on full screen, the RenderTarget starts moving. Do you have any idea why this would happpen ? Thank You !

Hey does that follow players while teleporting?

Thanks for the tutorial, I took the system you built during the "Create Line Trace System" section of the video to enable a cone shaped line tracing system for a football (soccer) game I'm developing. It looks asthough the system needs ~>50% of the line traces to be inhabited by another character for the desired player to become available to pass to (set by the "Out Hit Hit Actor"), do you know if its possible to set the "amount of traces required" to a certain amount? Thanks

Awesome tutorial, thank you so much!

How can you make the vision Cone angle and the vision circle diameter shrink as the player loses health and also when the player jumps? would really appreciate an explanation, Great tutorial btw!

Wow, your video is so wonderful!!! It solves all the problems I'm facing! Thanks a lot!

Got a question for you, Is there a way to do this, or something simular to how League of Legends works. By that I mean, you can still see terrain and such out side the radius or view, but mobs and players are not until they are inside the area?

Hey, my scenetexture isn't working, gives the lerp an error, even with the R,G mask

realy thx, just how can i up the size of the triangle pls ?

Hi is there a way to make the vision cone became a bit longer?

GOOD JOB！！！！！

IS there a way to make the transition from what you can see to black less harsh/hard, more smooth/blended?
