I did some lab tables, and when i run it.. The player can pass a little of that desks.. What is wrong.. In this shot bellow, you can see that the models has a correct origin and that stuff....
models will always be like that its best to add invisible geometry to the layout of the model. That way the player can easily interact with it and use it as a way of jumping onto or hiding behind. Models are usually pasaable in some sense.
the think is that .. I guess is not need..cause The disk now have newton .. and then You can interacte with them ..life you can make them fall, of course i have to but a mass that is ..
hum..it worked for some side of the table..but it make now some ares where there is no table blocked..so i think i will use true colision(newton or physics)
