really need help

okey so im making this smal flappybird game, and the obstacles are showing up randomly between a limit i sat. but for some strange reason the tree first blocks spawns way too high, it is kinda hard to explain, but if anyone could check it out for me, and report the problem i would bee very happy!!!

it is on level 3

@“Magnus Aalde” you have an always trigger hooked up to the eval input of your expression, the expression is set to A-256, but the A in your expression is set to 0 by default, meaning the first output is always -256, delete the always trigger, and set your random number to input into the eval
Hope this helped

thanks @SnakeInMyHoot , at least i know the problem now!
