So here in I have a Climbing System allowing grabbable ledges and if anyone knows what can drive a curve via launch velocity i would like to know how it could be achieved?
here’s latest progress Tomb Raider - WIP Title Climbing System (UE4) - YouTube
example to achieve
Just to bump this up as it is unsolved.
Basically, there are two different solutions to your problem.
- Set your jump and air control settings and then place your ledges so that you can reach them.
If your character is in a certain radius to your ledge, then grab the ledge. Use motion warping or similar to bridge the missing distance.
- Predict where a climbable ledge is, if your character jumps then calculate the velocity needed to reach that point. For this you can use UGameplayStatics::SuggestProjectileVelocity.
I recommend the first solution 
u wouldn’t happen to have a way to set that up or anything would u?
You can set it up in your CharacterMovementComponent and you may also want to change the default gravity of your game
