Hey guys, in today's video, I'm going to be showing you how to set up a homing projectile and/or missile for your game. This can lock on to any target you like, and it can also update targets while moving.

7:58 Depending on what you want your target to be, you actually need to set the class to your target's requisite collision component. Not doing this results in the bullet always aiming towards the floor beneath the target. For example, if the target is a player or an enemy, you need to set the class to CapsuleComponent so that it aims towards the center of the target.

@megtwin Жыл бұрын

I tried this but it will not allow me to select capsule component, it keeps changing it to capsule collision. How did you get it to accept that? I'm using v4.26

This is the only place I could find an explanation of how to do this after seeing several other videos where the author was inserting these with no explanation of how. It's not listed on the various blueprint "cheat sheets" that I looked at.

Awesome Tutorial, for anyone who is wondering why their projectiles are landing at the targets relative 0,0,0 location, the simple solution is within the "Find Homing Target" function of your blueprint, instead of "Get Component by Class", instead break out of your "Homing Target" reference and cast to your targets blueprint, then out of that you can reference the capsule component or even any component that lies within this blueprint.

@MattAspland 2 жыл бұрын

Thanks man, you could maybe use a capsule trace going straight forward X units from where the player is looking. It is basically a linetrace, but 3D. Then set the homing target to be whatever, if anything, the trace collided with. That way it has to be within a certain radius from the crosshair (centre of player's screen/vision). Hope this helps and makes sense :)

At 4:16 you have to use a Vector Get ABS node before getting the vector length otherwise it's using negative values and it ends up picking targets in the opposite direction.

Great tutorial but it works weird because the change of direction is always the same in time for a small change as well as for the huge direction change. I mean if player jumps to the side the rocket should not turn in 180 degrees ( huge direction change ) in the same 1second as it's doing the minor direction change

@SurviveOnlyStrong 2 жыл бұрын

found a way using manual set velocity: vinterp between current velocity and target velocity and when currentVelocity - targetVelocity length is > 100 set interp speed to 0.1 This way when a rocket need to turn too much to the target it just stops turning.

I have dragged my Static mesh onto the default scene root and the projectile now follows me.

Hello, I followed the tutorial, and it worked out okay. The only thing I'm having a problem with is when the homing projectile hits the target and the target moves to a new location, the homing projectile continuously keeps targeting the target's initial world location, instead of the target's new world location. How would I make the homing projectile target the target's new world location after it moves?

Hey man, this is what I want for my game however, the projectiles stop when they reach their target. Normally that wouldn't be an issue, but I'm trying to make a vampire survivors style game, so I'd like the projectile to keep going in its last direction without the homing . Any help would be great!

@Luillopanto25 2 жыл бұрын

Hey I am doing something similar. I am not home yet so I have not tried it, but I think what you can do is to put a "delay" node with a short amount of time, lets say "0.2" after finding the homing target location and then inmmedially setting the "is homing projectile" variable to false, so it will continue in that trayectory letting your target evade or escape your projectile. I have not tried it, but I think it should work.

For some reason the projectile goes to the enemy's feet and most times it hits the ground before reaching the target. I have disabled anything related to gravity in the projectile. If I have homing disabled, the projectile will go straight until it hits something as normal.

if you assign this logic to enemy and there is no more enemy on the map, it leads to error. this Logic is not useful for enemy. or for objects outside of value - in Float variable Closest Dinstance. Unfinished Blueprint. it works only for non destroyable objects on the map.

@Suthriel Жыл бұрын

You can prevent that, if you a) give your projectile an ArrowComponent as backup target, that is just a little bit offset from the center / in front of the projectile, and then B) introduce a branch in the code (before it enters the loop), that checks, if the array of found actors has a lenght greater than Zero -> If true, it goes into the loop, and if false ( = zero targets found), then you assign that ArrowComponent as target. With that, it will chase that ArrowComponent (which will always be in front of the projectile, because it is part of the projectile blueprint), if no other target is found.

@@Hyraxonable In my Homing Projectile Blueprint, where the ProjectileMovementComponent is, it´s as simple as dragging the ProjectileMovement Component into the Blueprint, then dragging a connection from it and serach for "Set Homing Target Component". That node accepts your Arrow component (and other components like Box Collision too). Not sure, if they have updated it (it works in my UE 4.27 version, aswell as in UE 5), so that it now can target other components too, not just Scene Components. In my Homing Projectiles, i either feed it the Arrow Component, if no valid Target exists, or the Box Collision Component from the found target (my chars use a box collision instead of a capsule, but that shouldn´t make any difference).

@Suthriel Жыл бұрын

@@Hyraxonable The condition for Lenght should be "equal to Zero" or "less or equal to zero". An array size of Zero is an empty array (no items =zero items in it), it can´t go into the negatives. An array with size one contains ONE item, and that one item has the Index Zero (the second item would have index One). Its slightly confusing, but the Lenght of an array is always one bigger than the Last index of an array.
