Algodoo

I guess I sparked an interest in polygon generation and modification again!

You did a great job of coding this one. I did notice a couple of little flaws, one you probably could improve, but the other would probably be VERY difficult if not impossible to improve. The first one is the fact that the vertices are rather "touchy" to adjust, and it can get frustrating after a while. I found that the vertices will sometimes get confused (or "tangled") with other vertices, and will sometimes fail to respond to the drag tool after a while. Moving the vertices very slowly helps in that regard.

The other issue which I'm sure you are aware of is the fact that the texture does not stretch and shrink along with the polygon vertices. Probably not fixable.

overall, nice job!

*Facepalm* Now bfdi fans using your laser without ask. And didn't gave you credits.

Can i use this laser im my scenes?

Xray,

I agree with everything you mentioned and appreciate your feedback. I'm not sure yet if and what I will fix.

Pootis-Man,

Yes.

Here is an "automatic" method to control vertex display:

update = (e)=>{
app.drawVertices = sim.running
}

This way, there is less chance of people leaving vertices displaying for all future scenes when they exit THIS scene.

EDIT: Also, you can leave out step #3 of the instructions.

hey, ever since i used this, it messed up algodoo for me

Xray,

Good idea. Thanks.

SkylanderSam06,

Sorry about that. The scene has been updated and will fix it.

Maybe add:

update = (e)=>{
app.gui.playmode = sim.running
}

So that the "S" key doesn't change the cursor into a Spring tool.

Done. Thanks.

Homer looks good now!

Nicely done

Kilinich,

Thanks for the comment and rating.

glitchy
when i press i my algodoo crashes

and when it works its really slow

applejack,

Sorry to hear that. On my PC everything works and the slowest thing is dragging a node, and that only takes a few seconds. In any case the simulation runs at over 90% of the simulation time when dragging nodes. How fast is it running on your PC? Select "File > Show sim-info" to display Sim-info.

Congrats! This is so usefull for me, that i thank you 10000 times
e.g. in optics i can let pupil modify lenses, mirrors,
in mechanics the brachistochrone-problem ( let a ball roll from A to B in the shortest time, the path it takes should be modified, and as result will be close to a cycloide ) becomes really interactive.
so:

Thanks for the compliment and feedback.
