Hello I have just uploaded a video showing the issue I am having,
I have a third person shooter project, I use blend space to mix the different running animations and the aim look and down. I copied the logic from the shooter game example.
In the video I start off by showing the different animations in the Running blend space: Run forwards, Run Backwards, Strafe Left/Right (during the animations the character is always facing forward). The I show the other blend space i have for aiming: Aim up/forwards/down.
Then I go into the animation blueprint and when I play the running blend the results are different, when the player runs to the left the character’s spine rotates 90 degress to face left, and when the player moves backward the character looks up.
Disconnecting the aiming blend space in the graph seams to resolve it but I dont know why. the variable ‘Direction’ is not being used anywhere else but its affecting the animation. Also if I disconect the variable that is feeding into the aiming blend space it is still messing up my running animation.
the code below is wht im using on my character, its just a modified version of the first person shooter template code, the variable AimUp is used to control the aiming blend space but u can see it is no way effected by direction, the variable used in the Running blend space. the MyAnimInstance.cpp/.h is straight forward, it just sets all the variables used in the AnimInstance to 0.
