Predict projectile path

[toxicrecker]

Describe the project you are working on

I am working on a 2d angry birds game.

Describe the problem or limitation you are having in your project

I want to predict bird's path trajectory before the bird is launched (something like this). However, i still didn't achieve this and i find it very difficult to achieve as a newbie.

Describe the feature / enhancement and how it helps to overcome the problem or limitation

A function to predict path in Rigid Bodies will be really useful for this.

Describe how your proposal will work, with code, pseudo-code, mock-ups, and/or diagrams

A function to predict path of Rigid Bodies, something like predict_path(Vector2 launch_velocity)

If this enhancement will not be used often, can it be worked around with a few lines of script?

It shouldn't be easy to implement an accurate path predictor, especially a newbie like me so I doubt that it can be worked around with a few lines of script

Is there a reason why this should be core and not an add-on in the asset library?

This is a great feature for a game engine to have, people might need it often.
