Hi Ferginator,
Here is how I create mine. There are different methods depending on what you want to do. This will get you started though.
The first image is just my BP component that is setup with a static mesh and a box for collision to generate the on overlap event
In this second image in my blueprint layout.
You’ll want to cast to the player from the generated overlap event. To get the launch character node you’ll need to turn off the context search checkbox when you drag out from the cast to character node.
In the Launch Velocity if you change the Z amount it will control how high your character is launched. I would suggest pulling off a node there for “Make Vector” then making variables in the panel to the right for the XYZ and making them editable. You can then edit them in the details panel when your BP is in the scene and you will not have to open the BP everytime or have separate ones for each jump pad.
If you have setup your GitHub account you should be able to get to the Unreal Tournament build there and take a look at the JumpPad that is being used. I would think that was setup all in Blueprints but have not looked at it though.
If you have any questions feel free to ask!
