Aurora Devs

Project crashes with UE5? Assertion failed: (Index >= 0) & (Index < ArrayNum)

Create another Replicated Vaulting and Mantling project with UE5 and make sure that:

The path to the project isn't too deep. In other words, keep the folder where it resides close to the root of the drive (eg. D:/UE/<project>).

The name of the project isn't too long (try "RVM").

If that doesn’t work then try the following steps

Create another Replicated Vaulting and Mantling project with UE5

In your folder explorer, go to <Project Directory>\Content\AuroraDevs_RVM\Blueprints\Character\

Move the Manny and Manny_UE4 folders outside the project folder (to your desktop, for example)

Run the project for the first time (this time it should not crash)

Close the UE Editor

Move the Manny and Manny_UE4 folders back into the project folder under the same path <Project Directory>\Content\AuroraDevs_RVM\Blueprints\Character\

Open the project once again

this archive⁠

⁠

Copy the Content folder from the extracted archive folder

Go to your newly created project folder (the one containing the .uproject file)

Paste the Content folder you have copied in this folder

Open the newly created project

Go to AuroraDevs_RVM/Blueprints/Character/ and open BP_ThirdPersonCharacter

Click on BP_ParkourComponent in the Components Tab

In the Details panel, scroll down until Mantling Low Animation Settings category and replace the animation montage with ALS_N_Mantle_1m_RH_Montage

Scroll down until Mantling High Animation Settings category and replace the animation montage with ALS_N_Mantle_2m_Montage

The ALS montages are retargeted to our UE4 Manny skeleton. Our UE5 Manny can use these montages since the skeletons are compatible. If you’re using a different skeleton, you may need to retarget these montages.

Use the following settings (You can tweak them if you feel the need)

How do I attach the character to a moving obstacle while vaulting/mantling on that obstacle?

Re-plug those events to their functions

❗ Keep in mind that this is a Work in Progress which may not work as expected for the time being.

Why is my character jittery during vaulting/mantling/sliding

p.NetShowCorrections shows Server correcting Client position on Tick?

Go to your character blueprint

Select the BP_ParkourComponent in your character’s components

Try either disabling or enabling bIgnoreClientErrors

bIgnoreClientErrors: If true, we should ignore server location difference checks for client error on this movement component. This can be useful when character is jittery during vaulting/mantling/sliding.
