Hello,
I was wondering if anyone could show me how to create a basic telegraph in unreal engine 4. I am trying to get it to act a lot like the telegraphs in Paragon like Gideon’s meteor or Aurora’s charge ability. I have looked all over the internet for a tutorial on how I can implement this but to no avail. Can someone show me how to do this or point me in the right direction. The telegraph also needs to follow the terrain of the map. Thanks in advance!
Do you mean teleport? If so use the Teleport node and set the location and rotation…in this example on BeginPlay the actor is teleported to a random reachable point within 250 units after 5 seconds:
no unfortunately not. i need a visual telegraph that will signify where the spell will cast once the left mouse button is clicked
yes kind of. here is a vid that shows a telegraph. its the blue shape on the ground that signifies what area will take damage when the ability is cast. Also notice how it follows the terrain.
Oh now I understand what you mean…Do you need it to arc as in the a flying arrow or projectile or just like a straight line with a decal to show area of effect?
I am completely unfamiliar with Paragon…something like in the video but not so specific to a cannon? Video:
Gotcha, it looks like just a decal that is rendered in front of the character, the one in my video is meant to just be a demo/starting point and not a completely perfect and polished finished product…Since it is relatively static per the player location you can simply create your decal and add it to the playerBPs components and set its visibility on and off as you need it. The shape and look of it will all be done in the material setup. If you have you textures for the shape and effects just create a new material and set its Material Domain to Deferred Decal and build it from there.
The damage effects in the video are all particle systems that spawn and most likely have either radial damage applied or use a direct damage apply on overlapping actors.
I am not sure of any tutorials that will cover this completely but search youtube for the individual parts for making a decal and applying radial damage etc, also these should get you in the right direction:
Do you mean where the mouse pointer is on screen or just the direction the character is facing based on the movement of the mouse? The setup I described will do the second bit but won’t render the decal exactly where the mouse pointer is on screen.
thank you for this it helps. so would this include is showing the decal and being able to move it while its being shown? so more or less have it show the decal based on where the mouse is pointing?
right where the character is facing based on the mouse. what i am trying to avoid is actually placing the decal and not being able to move it when it shows up. pretty much the order will be: press a button, the decal shows and moves around when the character moves and then gets removed when the user presses the left mouse button.
thats perfect can you show the BP or code that you used to accomplish that?
Exactly what I described above…here’s the characterBP like I described with the decal added to the components and positioned in front of the character:
And here is the mat with the settings for the decal:
perfect thank you for the help!
Like this: Decal Rendered in Front of Player - YouTube This is the quick result of the process I described
As a non native English speaker i was looking for a long time now videos about “ground telegraph” / “attack telegraph”, and i think this is the word i had to search for. Just being thankful 
For anyone still looking for a good beginner tutorial on this, I’ve made a couple videos demonstrating how to make a simple telegraph, and then how to make it work on uneven terrain using decals:
