Re: [pygame] Make a sprite fall with realistic gravity?

[inigo delgado <inigo.delgado@xxxxxxxxx>]

By the way:

Pixels are integers, so don't make operations with them, make a variables like:

varX = 0.0
varY = 0.0

And make operations using them or you will lost the decimals (because x and y in the image are integers: pixels). This is visible  when you do a bouncing animation, the animation gradually will lost speed and finish -after many bounces- in the floor, like if it have been a friction force that have stopped it.... So make all operations in a separated variables and before to draw the objects asign the results to the object position (so in the next interaction you will have the exact x and y coordinates to operate with and not something rounded to 'pixels' -int-)

Thanks guys, your replies were helpful. The physics links in
particular were very good for refreshing my memory on the equations.
