Question

Hi all,

Just wondering if possible. I haven’t been able to guess this one so far. I’m probably missing a small velocity or attribute somewhere…

Currently, when a race car drives near to a bush or tree, I’d like the birds to explode outwards and fly off in the direction they are facing. I’ve loaded in the bird’s animated sprite, but direction wise, they currently swoop and fly backwards, sidewards and any non straight direction. I’ve not been able to find an orrientation to forward velocity as yet.

Here is the picture of what I was trying to do, with arrows. Anyone have any hints, can this actually be done?

Many thanks if someone knows.

If i understood correctly, you are using GPUParticles2D.
There is checkbox Align Y in Process Material → Particle Flags.
It will “Align Y axis of particle with the direction of its velocity.”
If birds will fly backwards, just flip the sprite before importing in project.

LillyCherry, you’re magic!

Thank you so much! I’d never have found that. :smiley:
