basically i want the player to move towards the last touch spot (but not snap touch to it).

similar to Scratch which has a follow last mouse click... the player is on an infinite loop moving forward 1 step at a time (which i have not shown in the following diagram):

i figure to do this, i have to work out the inverse sine (arcsin) of an angle (i have already calculated opposite / adjacent / hypotenuse [using pythag theorem]).

********PROBLEM IS HOPSCOTCH DOESNT HAVE AN INVERSE SINE FUNCTION FROM WHAT I CAN TELL AS SHOWN IN FOLLOWING SCREEN CAPTURE********

as shown (from what i have so far) i am only given the following set of operations: { sine, cosine, power (e.g. x^y), square root, basic arithmetic (+ - / *) }. i have to do it on the fly within the app itself as the player moves - so please dont tell me to use a cowculator!!

i realise the solution if player_x < touch_x then increment player_x until.... this will move in diagonals however (great for 45 degree touches) but not in a direct path. is there any other solution that doesn't involve inputting a set of trig tables (i.e. blunt force??)... I just hate the snap drag to finger!!! will hopscotch be updated with these functions at some (near) point in the future?? I'm using the free version - does the paid version have such functionality??

thanks so much!!
