RaUnit scripting

[Kilinich]

Building new type of RaUnit I've pick RaRaMalum's idea of solid booster and make some improvements:

1) Here it is simple and clean script to get hidden values (applied to box onHitByLaser event):

Code: Select all

onHitByLaser = (e)=>{
        sim.time < controllerAcc ? { //run it once on start
            controllerAcc = sim.time;
            e.geom.body := 1;      // set any value to body to get real value after undo
            e.geom.geomID := 1;  // set any value to geomID to get real value after undo
            // same trick with any other hidden variable
            e.laser.onLaserHit = (e)=>{
                e.laser.onLaserHit = (e)=>{};
                app.step;
                app.undo
            }
        } : {controllerAcc = sim.time};
       
       // do some stuff you need
}

2) I've replace originally fixating with gluing. That gives me ability to spawn circles on a distance and not count geomID. So just add "body := e.geom.body" and that's all.

3) I've replace hinged killer with spawned killer. Again, that gives me ability to spawn ad kill on a distance and remove parasite forces, generated by hinges.

4) Finally, I've add g-force to spawned circles and compensation multipliers to make it possible to run on any sim speed. I've spend a lot of time to find ultimate formula
This is closest one: Vel := Prev_Vel - [0, Sim.gravityStrength * (Real_Timeinterval + 1 / sim.frequency) / 2]
Means additional velocity is G*dt and dt is average of real time tick interval and 1/freq.

Here it is result script:

Code: Select all

    onHitByLaser = (e)=>{
        sim.time < e.geom.textureMatrix(0) ? {
            textureMatrix = [sim.time] ++ e.pos ++ [0, 0, 0, 0, 0, 0];
            e.geom.body := 1;
            e.laser.onLaserHit = (e)=>{
                e.laser.onLaserHit = (e)=>{};
                app.step;
                app.undo
            }
        } : {};
        textureMatrix(0) < sim.time ? {
            textureMatrix = [sim.time] ++ e.pos ++ [sim.time - textureMatrix(0)] ++ (e.pos - [textureMatrix(1), textureMatrix(2)]) ++ [0, 0, 0];
            friction = (e.normal(0) == 0) ? (e.normal(1) < 0 ? math.pi / 2 :  - math.pi / 2) : (math.pi * (e.normal(0) < 0 ? 0 : 1.0) * (e.normal(1) < 0 ? 1.0 : -1.0) + math.atan(e.normal(1) / e.normal(0)));
            scene.addCircle({        //right stabiliser
                pos := e.pos + e.normal * 100;
                collideSet := 64;
                color := [1, 1, 1, 0.5];
                body := e.geom.body;
                drawBorder := false;
                drawcake := false;
                density := density;
                killer := true;
                vel := [textureMatrix(4), textureMatrix(5)] / textureMatrix(3) - [0, Sim.gravityStrength * (textureMatrix(3) + 1 / sim.frequency) / 2];
                angvel :=  - friction * restitution;
                airFrictionMult := 0
            });
            scene.addCircle({      //left stabiliser
                pos := e.pos - e.normal * 100;
                collideSet := 64;
                color := [1, 1, 1, 0.5];
                body := e.geom.body;
                drawBorder := false;
                drawcake := false;
                density := density;
                killer := true;
                vel := [textureMatrix(4), textureMatrix(5)] / textureMatrix(3) - [0, Sim.gravityStrength * (textureMatrix(3) + 1 / sim.frequency) / 2];
                angvel :=  - friction * restitution;
                airFrictionMult := 0
            });
            scene.addCircle({     //right killer
                pos := e.pos + e.normal * 100;
                heteroCollide := true;
                collidewater := false;
                collideSet := 64;
                color := [0, 0, 0, 0.5];
                drawBorder := false;
                drawcake := false;
                density := textScale;
                killer := true;
                vel := [textureMatrix(4), textureMatrix(5)] / textureMatrix(3) - [0, Sim.gravityStrength * (textureMatrix(3) + 1 / sim.frequency) / 2];
                airFrictionMult := 0
            });
            scene.addCircle({       //left killer
                pos := e.pos - e.normal * 100;
                heteroCollide := true;
                collidewater := false;
                collideSet := 64;
                color := [0, 0, 0, 0.5];

                killer := true;
                vel := [textureMatrix(4), textureMatrix(5)] / textureMatrix(3) - [0, Sim.gravityStrength * (textureMatrix(3) + 1 / sim.frequency) / 2];
                airFrictionMult := 0
            })
        } : {}
    };

I've spend a lot of time to find ultimate formula

You mean you just made this formula with trial and error?

well, yes, I've try many combinations and iteratively comes to this.

[KarateBrot]

phew that's a lot of work

[Mystery]

How is that even possible!

[fox11trot]

ok so ive looked at these scripts many times and i dont really understand how it all works.

i understand that there some variables like geomid that cannot be read or written but how does this make it possible?

and what are some other hidden variables?

[KarateBrot]

and what are some other hidden variables?

Just look at the .phn file in a text editor.

[fox11trot]

so you can read velocity and position?

and my other question is more important

[KarateBrot]

so you can read velocity and position?

and my other question is more important

Oh sorry. I thought you mean something different. For example if you make a variable scene.my.var = { scene.my.this - scene.my.other } it always calculates the difference of scene.my.this and scene.my.other but you can't see it in the scene in algodoo. To see the code of the variable you have to look at the .phn file.
If you're talking about velocity, geomID and stuff that's something different. You can't get them but when spawning an object you can assign this object for example a specific geomID so you know what geomID it has got. Or you can get it from a preexisting object with "new method" / "method x". I don't know what the official name of this method is.

[fox11trot]

ok so basically you can get geomid and body numbers

i think i kindof understand it
