Predict Collision

[Miroku_87]

Hey everybody,

I'm looking for a way to check if a sprites encounters another sprite on a given trajectory BEFORE it evens starts moving.

That's because if the sprite will collide with an another one while moving in that direction I don't even want it to go.

 

Can somebody please explain to me how can I accomplish that?

 

Thank you in advance!

Thank you valueerror I will take a look at it!

You can also check one of my blog posts here: http://nightlycoding.com/index.php/2014/01/remote-collision-detection-for-games/

 

Here I find the angle where the two objects meet and I stop the rotation of the canon when the right angle is reached, without them colliding or even be close.

Thank you MichaelD but maybe it wasn't clear that my question wasn't about how to do it regularly.

I know methods myself, but I was wondering if Phaser came in help to developers with a quicker way.

 

Thank you the same

a willithitsprite() function that returns the sprite?  uhh.. i could use something like that..

[Miroku_87]

Yes exactly!

But well, if it doesn't already exists I will do it myself =)

I imagine something like that in the physics engine should be fairly easy to add? If you know the velocity and size of both objects, you can make an accurate prediction for whether they'll intersect at some point in the future. I guess it'd have to be a simplistic prediction though, as gravity, drag, collisions and so on will all muddy the waters. Maybe gravity and drag can be added to the equation but collisions will make it much more difficult.
