How to make a vehicle's boost when you hit an area

Hi, I’m making a skate park game, but for wheelchairs. I need help on getting a speed boost to work. I made a blue print of a mesh that says Boost. I’m trying to change the vehicle max speed, but I can’t figure not how to call the vehicle’s speed into the boost’s blue print

Thank you

On Event Overlap - other actor → cast to chairBP from the return pin grab whatever variable you want. How is the wheelchairBP setup, is it setup as a wheeled vehicle, character or a pawn with movement component?

That should be Other Actor not overlapped component, I will take a quick look at the demo vehicleBP real quick to see what needs to be set for a boost to work on overlap

For now, I’m using the demo vehicle. I have On Event Overlap to Cast to Vehicle bp. From there I can’t set vehicle rpm. I can’t find that in the bp

I know this isn’t right

I’m going to put together a quick Demo video of what I setup as a boost give me a few and I will post the link and the BP setup.

That is for a character not a vehicle, they are looking for a vehicle speed boost

Is this the type of effect you are trying to achieve: Vehicle Speed Boost Rough Demo - YouTube

I looked at that, but the vehicle has no "max speed "

Yes, that is what I want

Ok this isn’t polished or perfect but with some tweaking you should be able to get it working the way you want. Here is a screenshot of the BP I am using for the overlap:

thank you, I’ll try it and I’ll write to

Ooops. I’ll write tomorrow

on the vehicle bp, how did you do the OldTick under the event graph
How do I give you karma

OldTick? Oh no, I’ve slept since then…also I have no idea how you give me Karma, I think the only way is to accept the answer or upvote it.

Ah I just reopened the project the OldTick is just a custom event and I am calling it from a better location in the BP so the links wouldn’t get crazy. I forgot I actually left that in there, that is how you can use a key input to trigger the boost. The video is a demo of the BoostBP and not the Sedan code, that was just in there during my testing.

it works when I push a key

Black Phonyx, do you think the size of the vehicle makes a different because I tried it with VehicleAv, the buggy. It doesn’t work unless I push a key. Any suggestions? I built everything around the buggy size

Size doesn’t matter, check your nodes…you didn’t edit the BP to work for your vehicle is all…here take a look at this:

Works fine for the buggy for me, like I said check your nodes.

I found what I did. I didn’t change Get Overlap Actor

Thank you
