Full Version: When is a brick wall not a brick wall?

OK so I have attached my project files here and I shall try and explain my problem.

I used a brick plugin to build my wall, it built my wall and I told it to leave no gaps, problem was that it DID leave a tiny gap, so when I calculated the physics the bricks just fell on each other and then collapsed the wall before my character could walk through it.

So last night I tried to correct that and moved all bricks manually so they are on top of each other, now the wall won't fall at all my character just walks through it. I really need some help here - I'm slowly learning but at the moment I am crap and I can build a model but animating is difficult for me as you will see from my crummy walk cycle.

I do need a hand trying to make a run cycle - anyone know of any running tutorials?

First and foremost here are my project files.

Thanks

I had problems loading your project. You should embed the files

Yeah thats what I thought, I had to go to work this morning and I was running late, I thought I might need to do this. How do I embed the files?

Thanks

and Also Thanks for looking smile.gif

Simply select Project->Embed All. If you then select Project->Consolidate->Project as text (*.PRJ) and Zipped (*.ZIP), and upload it, then all the files needed should be there

What I have seen on Your brick model .
- all normals are pointing in the false direction
- you have innerpatches (in the newblockey model too)
- the brick model should be centered at X/Y/Z 0 , otherwise the brick plugin fails (the extraspace between the groundplane and the first row is coming from this)

I have attached a workable brick model
And as a suggestion , go back first to the spline modelling basics , it's look like You are coming from a polygon program (the newblockey model...)

Excellent thank you for your feedback, I think it's important I do go back and get this done properly. The Blokey model is essentially a square character which I am trying to model in 3d (for older versions of what he looks like go to http://www.blokey.net)

I didn't realise that inner patches were a bad thing although I do remember how I attached the legs on the giraffe, so I should do this for the arms and legs of my model, to make it one complete model.

Thanks and thank you for the updated brick model, I shall have a look at that tonight

What I have forgotten in my last post .
Why it is needed that the brick should be centered at X/Y/Z 0, is the fact , that the center of mass is calculated from the position in the modelling window .
And if the center of mass is at a different point, You get also a different behavior for the model .
It can be changed with the Calculated CoM option , but this is not recommended way.

ahhh! That totally makes sense! I didn't think about it like that. Thanks!
