I was trying to make an explosion animation using letter. It was supposed to spiral out, then kind of cover the screen in a bunch of the letters, but I couldn't get the spiral working in under 10 line of code. Any help shortening it?


Code:

Output(5,13,"0
Output(6,12,"0
Output(7,13,"0
Output(7,14,"0
Output(6,15,"0
Output(5,17,"0
Output(4,16,"0
Output(3,15,"0
Output(3,14,"0



Just add a couple more outputs and there you have it.

What it should look like:

o
o
o
o
o
o
o
o
Imagine those O's in a cicle.

Thats the general gyst of it. It oviouslyy makes a full circle on calc.

Heey Unicorn, what you can do is something like this:

Code:

Radian
0->A     // The polar variable
0->B     // The distance from the midpoint
For(C,1,100
Output(6+round(Bcos(A),0),13+round(Bsin(A),0),"O"
B+.2->B
A+.3->A
End

Of course, you must check for the mininum and maximum values of the screen. This is a simple spiral of "O"'s. I based it on the polar mode. Hope this helps!
May I ask, what C is? Is it just a random variable that equals 0?
How could I make the spiral tighter, and limit how far it goes out?

To make the spiral tighter, just change the part that has B+.2->B and A+.3->A into a smaller number to add to it, like .1 and .2. The distance that it travels out for is changed from the For( loop. The variable C is just a random variable used in the For( loop. Search for what For( does, very useful.

C could be replaced with any variable. For further explanation: The For( Command

I looked it up a couple of hours ago, thanks for clarifying what I read.
