Summary

Hi Community!   I am having an issue with a core plugin for our project called "TMJumpAction". I'm trying to setup evented encounters. The event has been set up with random movement and event touch ( I tried player touch also, same result ). When the event and player make contact (it makes no difference which one initiates it, i tried it both ways) the game crashes with the error:  "Reference Error" normal is not defined

Hi Community!  

I am having an issue with a core plugin for our project called "TMJumpAction". I'm trying to setup evented encounters. The event has been set up with random movement and event touch ( I tried player touch also, same result ). When the event and player make contact (it makes no difference which one initiates it, i tried it both ways) the game crashes with the error: 

"Reference Error"

normal is not defined

This error does not occur if the player touches the event from above. Only with player contact from below, left side and right side. This error only occurs when the event is given autonomous movement and touch triggers (player touch or event touch). I reproduced this error in its own project with TMJumpAction as the only plugin. I am uploading a demo of this error and posting a link to the plugin here as well. I have sent the author of the plugin a message as well, but I am not sure if he/she offers support for it anymore or will get to the message (perhaps language barrier or very busy)

Community, I really am thankful for how supportive we all are of each other. I am particularly thankful that each time I have personally sought help, someone has always been willing to help. For that thank you all! I really hope to make a positive mark on our community and I really hope our game makes a huge and positive impact on the RPG Maker Brand and community. Thank you all in advance for checking this listing out and anything you can say or do to help us I greatly appreciate! This plugin is crucial to our game, without it or another gravity plugin, I'm afraid I will likely have to reconstruct the vast majority of our game. Please help us if you can and thank you again for checking our plea! Have an awesome day!
