Question
This is an extremely odd issue I’m having, but I’ll try to explain it the best I can.
I’m pretty sure it’s a bug, but just wanted to check here befor I report in case anyone is having the same issue?
What I’m trying to implement
So the feature I’m trying to implement, is multiplying the movement speed of an entity accross it’s entire animation length (based on a curve).
e.g. The entity would start at 40% movement speed, but towards the middle of the animation, it gets sped up to 100%, then back down at the end of the animation:
2 Quick Notes
- I tried getting the playhead position of the AnimationPlayer node, but since I have a Time Scale node in my blend tree, the length of the animation is different between the AnimationPlayer and the AnimationTree. This is why I have to use the state machine’s methods.
- I thought about directly altering the movement speed by simply keying in a value in the animation directly, but I’d then have to do this for all 8 direction animations, so I figured using a separated curve is easier.
Anyway, here’s the code I came up with:
if sync_movement_to_anim_curve:
var current_play_position: float = state_machine.get_current_play_position()
var current_length: float = state_machine.get_current_length()
var animation_progress: float = current_play_position / current_length
movement_speed *= anim_movement_curve.sample(animation_progress)
The Issues
-
My entity scene gets completely wiped off the map (doesn’t render) when it spawns in
-
The TileMapLayer node I’m using (completely unrelated and in a different scene) has missing tiles and a jumbled
z_index
-
I’m also experiencing random flickering that’s difficult to reproduce
It’s also important to note that I’m not experiencing any warnings, errors or crashes, and all the values are correct when debugging.
Thanks for reading this all if you’ve gotten this far; sorry for the wall of text!
Any input would be greatly appreciated though 
Again, I’m pretty sure this is a bug, but would love to hear if anyone has any insight.
Thanks!
