Check for blocking objects on jump

Development Programming & Scripting Blueprint

Hey there,

I’d like to be able to predict if my jumping character can reach the gray position, or if he will crash into the block’s pink face.

I thought of a capsule trace amoung the “jumping route” but wasn’t able to recreate the curve of the character flying. May some of you guys have the solution or even a completely different idea on how to predict the characters flight.

Thanks for your time and help! -Dominik

To calculate the curve you can use the* Parabolic Curve* that is fairly easy Parabola - Wikipedia or the Bézier Curve.

Have a look at this tutorial:UE4 Projectile Trajectory Tutorial : Part1 - YouTube
It actually implements a parabolic curve used for Projectile Trajectory.

To get the velocity, you can just get the MovementComponent’s current velocity, and calculate the curve, the Gravity in UE4 is -980 by default.

I hope it helps. :slight_smile:
