Using velocity to move one object towards another. - Printable Version +- 2DWorlds Forums (http://2dworlds.buildism.net/forum) +-- Forum: 2DWorlds (http://2dworlds.buildism.net/forum/forumdisplay.php?fid=4) +--- Forum: Scripting (http://2dworlds.buildism.net/forum/forumdisplay.php?fid=13) +--- Thread: Using velocity to move one object towards another. (/showthread.php?tid=2188)

Using velocity to move one object towards another. - Scripter - 04-04-2011 This is mostly a math question, but how would one use FixedVelocity to move one object (In this case, a Circle) towards another (Player's body)? I really want to finish my Chain Chomp ^_^ RE: Using velocity to move one object towards another. - Jacob__mybb_import1 - 04-05-2011 This is adapted from my gravity tool script. It hasn't been tested. [lua] force = 5 unitVector = box1.Positionub(box2).normalized --Get a vector with length 1 that points in the right direction box1.FixedVelocity.Velocity = unitVector:mul(force) --Multiply it by the force to get the new velocity [/lua] RE: Using velocity to move one object towards another. - Scripter - 04-09-2011 Thanks Jacob_! By making the force a negative, I managed to get it to work By the way, I'm curious if there is a way to move it only one way (up or down). I am also curious as to what :mul() is. RE: Using velocity to move one object towards another. - Jacob__mybb_import1 - 04-09-2011 If the x is 0, it will not affect x movement; same for y, mul() returns a copy of the vector with the x and y components multiplied by the given value.
