s1 and s2 must be under 1 and 2 objects ,their Z is lower than them but i couldnt make it. and if you play the project, the objects suppose to be under , sometimes flashes. just trying to do simple things but cant understand why it is hard in GD

for info, s1 and s2 are for collision .they ll have different collision masks so when they collide ,object and they ll be destroyed.
