Jump To ?

I’m new to Corona, have read the forums and docs, and can’t find a solution to this:

The main game character lives on the ground and must jump up from platform to platform until it reaches the top. Some platforms are accessible, some are out of reach. The user controls which platform the character will try to jump to by touching the platform. At this point I want to give a linear impetus to the character so that it would land on the platform in an arc. So, questions:

  1. To figure out how many newtons (if that the unit used by Corona ?) I need to give as impetus I’d need to know the mass; how do I find that out ?

  2. This is what I intend to do: from the ideal landing point I want to back-calculate the jumping arc to the character and determine how many newtons will be required and at which angle the character should launch. If the number of newtons is higher than K (the maximum amount of energy the character can spend on a single jump), I keep the launch angle but substitute K for the total sum of forces to be spent along the X and Y dimensions by scaling both back accordingly. Does that make sense ? Is this how I should approach the game ?

  3. Is using the linear impulse idea the best way to code this up ?

Thanks,

Brad

Yes sir. I use linear impulses. [import]uid: 29181 topic_id: 10093 reply_id: 36871[/import]
