Thanks, but how to convert Strings[] to int ?

GoToLoop

Convert the whole Strings[] to int[] via function int().
It's also a good idea to call trim() before int() for safety:

It work ... But I found another code !

GoToLoop

An example using float() to convert String[]. It's the same idea as int(): *-:)

size(200,200); int stars=152; String Star = str(stars); String star[] = {Star}; saveStrings("testsaveloadstring.txt",star); String Stars[] = loadStrings("testsaveloadstring.txt"); int test=int(Stars[0]); text(test,25,50);

I assume that you are going to be using small amounts of data (no more than a hundred or so variables). Otherwise, you'd be better off saving them in a direct manner. Also remember that floats saved as Strings can take up a lot more space than they need to, so you convert a float into a byte array before saving, then load the byte array and convert back to float.
This page details how to do that both manually, and also while saving.
