For such a action game with climbing, ladders and similar physical stuff, I miss falling damage for the player character. Therefore I added a simple fall damage system to it. Here it is, so you can implement it also if you like (see pic enclosed).
Add those to youre BP_TPPCharacter Actor in Event Graph.
You can fiddle around with the values to match youre game project, and after youre done, you can remove the print string node that helps you getting a feel for the z-velocity vector value on landing.
Regarding the values: 1250 is the z-velocity value under which no damage is happening at all.
Above that damage is applied: the first 1000 don’t “hurt”, but everything above it is divided by 35 (can adjust here) and subtracted from the player’s health variable.
At the end the “player get damage event” is primarily for shooting damage, but works also for falling damage technically.
Also i think the second branch for health <0 could be left out, but it does no damage to the damage system
