Hey! For those finding a Deprecated function. In the Construction Script, you need to Right-click and search for attachtocomponent, and there will be several options, like AttachToComponent (Mesh), AttachToComponent (Camera), AttachToComponent(LeftHandCollision), AttachToComponent(RightHandCollision). You need to add the Attach To Component for each collision, the variables will be instantly added, you just need to be careful that the HandCollisions are in the Parent socket and drag the Mesh variable, just like in the video, and attach it to the parent. Then you need to set the Location Rule to "Keep world" or "Snap to target" , whichever you find better. If this works, you'll see the spheres moving along with the target in the Viewport once compiled. For the Spheres to be more precise you should add a socket and use the "Snap to Target" location. Hope this helps!

I am confused because you can't have the mesh and the HandCollisions in the same parent socket. Should I make another AttachToComponent?

@AdamJanz3D 3 жыл бұрын

5:28 "Attach To" is now "Attach Component to Component" (shown when dragging a wire off of your LeftHandCollision component and searching for "Attach"). 7:12 "Attach Type" is now separated as Location, Rotation, and Scale individually. Choose "Snap to Target" for Location and Rotation, and "Keep World Scale" for Scale, to mimic the setup used in the video.

Simple Fix For AttachTo [ Engine V 4.22.1] : Q: Whats Wrong? A: Notice he only uses an ' AttachTo ' not ' AttachToComponent ' which also does not let you use your L or R hand Collision as the Target. Soloution: In your Character_BP, in the Construction Script tab; right click - search ' AttachToComponent ' get the one without brackets as I typed. Then drag a wire off of 'Target' In the "AttachToComponent", search for your Left Hand Collision. It will say under components [ "Get Owner 'LHCollision" ] *Note My Names For Hand Spheres Are Different: Left = LHCollision, yours will be different when searching* In the settings for "AttachToComponent" : - 'Location Rule' Set to Snap to target - 'Rotation Rule' Keep Relative - 'Scale Rule' Set to Keep World This is the equivalent of changing the old "Attach Type" - 7:19 Attach 'Mesh' to "Parent" as shown - 6:20 Repeat the process for your other hand. If you are signed in and this helped, leave a like as it could help out many!

Hi.. AttachTo is deprecated in lattest version... i'm strill figuring out what should be the replace for that method, can you provide? Your tutorials are great btw. Thanks.

@@ShellYoung Thank you, 2 Years later this is still relevant. I also changed the socket names in CharacterBP > Construction to middle_01_l and middle_01_r. That puts the collision spheres a little closer to the front of the hand which I felt was more accurate. It's possible to see the effects of said change by going to CharacterBP > Viewport.

Is much easier to set the collision sphere PARENT to a bone in the viewport. to do that: Just drag the sphere into the mesh (in the components pannel), Set parent socket to the correct bone, Then adjust the size and position to the character and Its done! 0% need to use the Construction Script

For those wondering why their punch is not moving the ball / why the collision is at their feet. Make sure to use AttachToComponent instead of attach to, set target as right and left hand spheres and parent "mesh". Set rules to snap to target. To see it in game more clearly open the right and left hand collisionspheres details and search for "hidden in game", turn this off and when you run the game you can see the spheres on his hands!

@andersonchong7625 6 жыл бұрын

Sry to interrupt, but i've checked all the statements that you have stated out, and it still doesn't work out. My character's hand just passed through the shapes instead of knocking them off. Then i tried to turn off the "hidden in game" thing that you have stated, the collision sphere is passing through the shapes too...

@Random Preston I am also using 4.9 and am not getting any crashes. I did do this a little different than shown here. Instead of using the construction script to bind the spheres to the mesh I just dragged them both to the mesh in the components sections. Not sure if that is a feature or not in 4.8 but yeah. Once it is parented to the Mesh you can go into the spheres details and select the hands as the socket to bind them. I hope that made sense.

@PuchoMacker 8 жыл бұрын

+Ramiro Linares The spherical collisions follow the animation even though they are not within the mesh. The quickest and easiest solution we could find was placing the spheres manually on top of the hands of the model. You can do this by going to the character's blueprints and in the viewport tab, selecting the spheres and moving them accordingly. Since they follow the animation, this method solves the issue.

If someone wondering how to avoid spamming of the punch animation, then just break the link to reset input on "do once" and drag to this input the link from the montage end sections.

I added an extra cylinder to be able to punch. Made it twice as big and have been messing around with the MassInKg. I can get it to where bumping into it has little effect but if I punch it, the cylinder will always go flying off like it was a really hard punch. How can I make the physic of the punch less extreme? Like make the sphere or cylinder react to the punch as if it were heavy and not light.

The problem with this video is that the hand colliders are only enabled while you are holding left mouse, not while the punch animation is happening.

@ec75413 7 жыл бұрын

Good Point. If this really matters, you can make two Notifies fired when PunchEnd animation finishes. And you may create a function for CharacterBP to make collision enabled. (This part is not really necessary) Then in EventGraph of CharacterAnimBP, let the new notifies calls the function (Or if the function is not built, just get the collision components and call SetCollisionEnabled) Mine for example imgur.com/a/F2kdG

it depends on your cpu, ram and most importantly video card. What are your computer specifications? I can tell you what you need to upgrade to get UE4 running smoothly.

Fists go right through the sphere in 4.16, rewatched video many times and was functioning perfectly up until this step, also looked over all the comments. I suspect it's a depreciation issue.

@TheThejokekid 8 жыл бұрын

it's because of how the collision is set to true, as it is in this tutorial, you only have collision while you're pressing the punch button

@MySGsuxballs 7 жыл бұрын

I'm not sure if you've already solved this but for future reference I personally wanted the players hands to collide regardless of animation so I just scratched the last half of this video and selected my collision spheres, went over to the details panel and under collision and collision presets I changed the drop down to BlockAll, nothing else seemed to apply collisions properly.

In the construction script, change to AttachToComponent (not the actor one) then leftHand goes into Target, Mesh goes into Parent and Location Rule set to Snap To Target. Same thing for the other hand. This solved the issue for me on 4.12.4 Good luck :-)
