**Tutorials and Tips / Moving chassis points by magic of BFE**

This tutorial is going to show you how to move chassis points that you usually cant move in ra2

Will try to make this noob friendly

You will need:

Notepad++

Brain

To start off, lets make a bot that is going to look like Apollo From Robot wars

This is as far as we can go in ra2

NOTE: The points that i Highlighted are gonna be the same position, and if i lower the points next to them that are highlighted green, i will get that sloped design that i drew

If you want to move the chassis points you will have to be in test robot section

Now you open up notepad and search for lines that have 3 number values (these are reference lines, yours will be different)

You are asking yourself, what do those numbers mean? Well, they are locations of collision and display mesh of the bot

Now to understand those numbers, here are pics i made

The centre point of the grid in ra2 is 0, The distance between each line in the square is 0.22

The best way of moving chassis points is to have a screenshot of both layers of the create chassis section

now i want to move the pink point to the blue point. To do that i have to figure out the location of the bot

We first need to locate the first X line of the point. The pink point is left so the value is going to be negative. The point cuts the -0,88 line so our first number is going to be

-0.88 Z Y

To locate the third point we again need to count down from the middle, and in this case the point cuts the -0.66 line, So the value is

-0.88 Z -0.66

The point we are going to move to has the same X and Z value but the Y value cuts through the -0.88 line

To find out the second value, we need to find out the chassis/point height

Now we know that the point is on the second layer of the area so the line will NOT have 0 as second number. How can we find out the chassis/point height?

In the 3 number values lines the second value that that isnt 0 is the height of the chassis/point, all of these lines that i selected share the same line

So the 0.78 is the chassis/point height

The line we need to find in the bot lab is:

-0.88 0.78 -0.66

So the line we are looking for is repeating 3 times

Why? It is simple, there are 3 meshes in the bot that game calculates

So to move the whole point we need to move all 3 meshes

So lets do that, by moving the Y points in the lines from -0.66 to -0.88

Exit the test bot area and:

The point is moved. Lets do that to the other side, by doing the same tactic of locating the points

Before moving the middle part, lets lower the parts that we moved before

locate the values that you previously moved (in this case -0.88 0.78 -0.88 and -0.88 0.78 -0.88)

Lets lower the second value of these numbers to 0.31

And done, the only thing left is to locate the top front points and move them back, again by finding out the location (in this case -0.22 0.78 -0.22 and 0.22 0.78 -0.22) and moving the Y location to -0.88

After we have done that it will look like this:

And we are pretty much done, hopefully some of you guys will figure this tutorial out, if you have any questions just ask me.

Enjoy
