Making missile going towards player0?

[Rabbit 2600]

I just realised I've forgotten how to make a missile go towards player0. I know it has to do something like if missile0x/y is less or more then player0x/y then missile0x/y +/- 1.

 

I tried this but it dosn't work. The effect I'm after is for the missile to go in a straight line towards the player and then pass him. Once it hits playfield it resets.

 

if missile0x < player0x then missile0x + 1
if missile0x > player0x then missile0x - 1

if missile0x > player0x then missile0x = missile0x - 1 else missile0x = missile0x + 1

if missile0y > player0y then missile0y = missile0y - 1 else missile0y = missile0y + 1
