Hey, look what I dredged up Very Happy So... I had copied this off the old forums into a text file, for reference without internet access. Now it's become useful again. Feel free to suggest corrections!


RigidChips English Documentation

Model structure

Five blocks, in a simple text file (you can use the .RCD extension)

Val {}
Describe your variables here. Body{} can use the variables described here as parameters for chips or global variables for scripts

Key {}
Key assignments : says which key changes which variable

Body {}
Model description

Script {}
automatic control and display of the data
Lua {}
Available from V1.5. Using LUA disables the script section.

Val {} description


Not case sensitive, except if used in LUA
To call a variable in LUA, you MUST spell it in upper case
You can declare variable()

default : Initial value Default: 0
min : Minimum Default: 0
max : Maximum Default: The maximum float (very high!)
step : the speed at which the variable naturally returns to its default
disp : indicates wether the variable and its value are displayed in the lower left of the screen (actually, anything other than 0 will display it). default : not 0

(here is the original translated text which discusses about conflicts between variable modifications by script/keys/automatic return to default. I don't quite get it)
Example: When with default=10 presently value is step=1 with 15, 15,14,13…11,10,10 it keeps changing.
However the Key {}, Script {}, Lua {} value being renewed in inside, between of the [ru] does not change.
However being renewed, when the change quantity 0 is, (the key {a: 0 (step=0)} script {a=a} and the like) it does not change

Key {} description

Key number: Variable identifier (step=...)

While the key is pushed, the value which is appointed to variable with step is added.You can add multiple affected variables, separating them with commas.
ex :

Body {} description

Direction: chip type(...) {…}

Direction= “N”, “E”, “W” and “S”

{} add here the chip which becomes the child (the chip which is connected to that chip). If none, just add {}

Chip types

The core - the base of the model. You can add it only directly under Body.
Weight: In. Aerodynamic drag: In. Friction drag: Small.
Fuel 2,000,000 (Ver 1.5B24).
Syntax : core()

Chips - the main construction element
Weight: In. Aerodynamic drag: In. Friction drag: Small.
Fuel 1,000,000 (Ver 1.5B24).
chip([angle=...]) angle on X axis
rudder([angle=...]) angle on Y axis
trim([angle=...]) angle on Z axis

Frames - no aerodynamic drag
Weight: light. Aerodynamic drag: None Friction drag: In.
Fuel 500,000 (Ver 1.5B24).
With option=1 ghost conversion (transparency, there is no contact decision)

Weight - heavy chip.
Weight: heavy. Aerodynamic drag: In. Friction drag: Large. Relative importance 4 times (2.Cool.
fuel 6,000,000
syntax : weight([option=1...8])
the value in option define the actual weight factor

Cowl - decoration chip. There is no contact decision and it is processed quicker than other panels.
Weight: 0. Shape changes with option
Cowls can only support other cowls.
syntax: cowl([option=0...?])

Power chips

The jet - thrust is generated in chip's Y axial direction.
Affect thrust with POWER. With effect smoke, with option 1 (hydrogen balloon), 2 (air balloon)
syntax: jet([angle=...],[power=variable],[effect=...],[option=...])

Wheel system - the chip which turns.
Appoint output with the POWER. Modify size with option. With effect thickness modification (contact decision change)
(here is some original text indicating tha you can also control the aspect of the rim, a bit obscure to me)
With the rim and the wheel 2chip minute, with name wheel side, name - rim side can be appointed with 1.
the rlw is a "non-reaction wheel". I don't know if it means no drag or no traction, or anything else. testers wanted Smile
POWER = torque ## of wheel (angular velocity + 100) ## 0.6

Arm - shooting weapon.
bullets consume energy, and energy takes time to recharge
syntax: arm([angle=...],[option=<strength of bullets>],[power=<energy bank>])

General options
color :R, G and B in hexadecimal. Example (red): color=#FF0000

spring : speed at which the chip returns to original angle after deformation. values=0...1, default 1

damper : necessary force to bend a chip. values=0...1, default 0.5

Name : give the chip a name, to use as reference in scripts

script {} section

The script is called to every frame.

IF conditional expression {…} : When condition is true, the {} block is executed. No "nestation"
GOTO xxxx / LABEL xxxx : jumps (spaghetti programming, anyone ?)
PRINT X,xxxx :X (0...100) is the line, xxx is the text to be printed (in "") or a numerical value, separate blocks with commas
Var1=Var2 : stores Var2 in Var1. If Var1 wasn't described in Val{], it becomes a local variable. Also note that global variables are not automatically initialized, so using a local variable is often best, for stability issues.
Example: dummy = _BYE (1)

Various operators

+ Addition
- Subtraction
* Multiplication
/ Division
= is equal
! = <> is not equal
> is larger
< is smaller
>= above
<= below
& AND, conditional expression
| OR, conditional expression

Here combined with this.

Previously (and currently) known as Juz.

Please do not write "LUA", beause it's "Lua". It's Moon in Portuguese, not a Limited User Account, Last Universal Ancestor, or the Lukla Airport in Nepal.
