You can use switch with floor:

t=...
switch floor(t)
    case -3 % -3<=t<-2
        x=0;
    case -2 % -2<=t<-1
        x=t+3;
    case -1 % -1<=t<0
        x=1;
    case 0 % 0<=t<1
        x=1;
    case 1 % 1<=t<2
        x=-t+3;
    case 2 % 2<=t<3
        x=0;
end

What have you tried so far? Folk here are very helpful for people with real problems. Real problems do not involve laziness.
