I used the collision of boxes that are placed in enviornment having two tables. I used the mouse cursor to grab the objects and placed in the other table. But i am facing one problem in case of collision detection between the objects. I used the proximity sensor for the objects and mouse when they are collided with each other ( minimum distance) then mouse picks/links that object. I am using the same sensor for collision also, some physics idea that are given in the documentation of vizard bt boxes are collided to each other but due to the gravity they are flying. i put the density as it is given in the documentation bt i does not works. Then idecided to move from this logic and try something else i tried to form the two proximity one for boxex collision and one between boxes and mouse but boxes are flying. I used the similar concept with crates that is define by vizard it work there bt not in the blocks. Please give some idea to resolve this problem. Here i am attaching thre function - one for hand , other for linking mouse and block and in last placing of blocks. In enviornment i already used the collide palne and collission for table also. So for collision what methodss i should go for because when i am working on same proximity sensors it will not works. All objects are placed in origin in vizard and then manually set the positions for plaing on table.`
