Hi <@1128706588539097099> and <@661194131929956358>, Let me share with you a few tips on governing the character’s movement

  1. Adjust the pawn movement component on the character, you will find parameters that can control the walking speed, acceleration and deacceleration and other important properties that govern the movement, you can find many resources online for tuning the movement component as well as you can simply experiment with it.
  2. when you ask the character to move to an object, it tries to move to its pivot, which in your case causes the character to go right through the object, you can fix that by a few ways:
  • placing an empty object right Infront of the quest object and name that object as the quest object
  • Add a collision around the quest object and then find a Boolean property named Can be stepped on or something along these lines on the object and make sure it is disabled.

Now regarding the character disappearing, I have a hypothesis that could be causing this issue, you see we have some logic running by tick on the ConvaiBaseCharacter blueprint, this logic basically keeps the character snapped to the ground by doing a ray trace from a point higher than the character towards a point below the character feet, and whatever point it first hits it will teleport the character to, so if the character accedintely collided with the room’s wall then the logic would teleport the character up the wall, or if the ceiling of the room is very low then the character would be teleported above the room, the only to fix that is to make sure the navigation mesh has some margin between it and the wall and that the ceiling is not very low

oh well not much success i put just a cube close by and it went to the cube but not real close it then says to it seems it cant find a pth to the cube. its odd for that to happen the path is clear and navmesh looks ok it shaded saying it is clear as well

It’s a bug that happens with Unreal nav system, try using an empty object to go to instead

Yes, it is an actor blueprint created like any other blueprint but don’t add any components to it

I think i solved it somewhat around my character i had a box for the narrative part of convai so when i removed that he seemed to have found the path ok

Reply by michael_34577 | 2024-08-05 15:32:58
