I want to know when my character up to peak , show another animation at this time, could you tell me how to judge it? thanks in advance.

If you assume the character's behaving like a projectile (ignoring drag, which means the result will be slightly off, since Torque does have aero drag), its vertical velocity is v0 + at where v0 is initial vertical velocity, a is the vertical acceleration (-20 in stock TGE) and t is time in seconds. You set that equal to 0 and solve for t to give you the time until the character reaches the peak of the jump.
Then you can schedule a function to be called with that amount of time delay - maybe cut it by a fraction to account for drag making the character peak before it would without drag.

I'd simplify it and use an equation to tell me roughly when the character will reach the top of the jump.If you assume the character's behaving like a projectile (ignoring drag, which means the result will be slightly off, since Torque does have aero drag), its vertical velocity is v0 + at where v0 is initial vertical velocity, a is the vertical acceleration (-20 in stock TGE) and t is time in seconds.
