loveframes column list selecting

Hi Does anyone know how to use loveframes column list selecting? I can't figure out how to get the column user clicks. In below code I'm printing the row variables but no row index there list.OnRowSelected = function(parent, row, data) for k, v in ipairs(data) do print("Column " ..k.. ": " ..v) end ...

You really don't want to get into the inverse kinematics of Box2d - it's way too complicated for such a simple problem.
Just use a mouse joint and you'll be fine.
Mouse joint is for user input right? I'm making AI based game, where AI throws passes..

Re: Physics object movement q

@Ivan thanks that probably works but ideally I would like to know how much force to apply so the ball stops moving let's say at 2 seconds

Re: Physics object movement q

The slow down effect of the ball would be nice, not just applying more force Your body already has damping so it should "ease" to a stop by itself. One hacky approach could be to make the force proportional to the distance: force = min(easing/distance, 1) * force where "easing" is the distance you ...

Re: Physics object movement q

How much force to apply depends on how much acceleration you want and how much does the object weighs. F = m / a Damping simply applies a force like this but in direction opposite to motion direction. Assuming that direction vs force angle mismatch isn't very important, you can simply increase desi...

And I can get distance to target, no problem there

Re: Physics object movement q

I just need to know how much force to put on the ball so it reaches the target

Re: Physics object movement q

Does anyone know the formula for this time = distance/speed Thanks I got the time formula but that was not my question The problem is that the rigid bodies in love.physics do not move with a constant speed especially when collisions and damping are involved. Yes but I only need to know straight mov...

Physics object movement q

Hi I'm using the physics library but my problem is I don't know how long it takes for the object to move to it's destination. Does anyone know the formula for this? If I have friction 0.25 then how much force I need to apply to the ball so it has traveled 300 pixels in two seconds? ball.body:setLine...
