Question, Prevent different objects sizes from colliding only in the middle

.

 

Using code tags properly

 

Can you explain what is going on in your screenshots? What is happening, and what do you want to happen?

 

Hi, i updated my Post.

 

Instead of a raycast downward, which is only the dimensions of a line, try using one or more BoxCasts. You can cast the dimensions of your entire block downward and check for collisions that way, or if your block is made up of many blocks, you can have each block cast its respective shape downwards to check for collisions.


Alternatively you can do more raycasts, one at each corner and in the center. If this is a grid based world (which it appears to be), then this should be reliable.

I cant find any support on Unity 4.7.2 for BoxCast. Or am I missing something? I cant upgrade to Unity 5, i have to work with that older Version.

I tried it with SphereCast but could not get it to work..

 

Is there a reason why you can't use trigger colliders for this?

P.S. Why can't you upgrade Unity?

 

Hi, I am doing my Bachelor Thesis and have to use the last Unity 4 Version. (Whole project is done with that version). When I enable a collider, the object starts hopping and jumping around when i move it.

 

Did you check the "Is Trigger" box on the collider?
