Solved cancel event only for specific blocks with on explode trigger

[ilovepancake]

Hi, I wanted to cancel event on explosion only for grass but cancel event cancel for every blocks.
I tried to remove the block from exploded blocks but that not working without error:

on explode:
  loop exploded blocks:
    if loop-block is equal to grass block:
      remove loop-block from exploded blocks

It should be possible because the tntwars in cubed craft, when a cannon explode, only the dispensers are exploded

Try This:

on explosion:
    cancel event
    create a safe explosion of force 2 at event-location
    loop exploded blocks:
        if loop-block is not grass or tnt:
            set loop-block to air
        if loop-block is tnt:
            set loop-block to air
            spawn a primed tnt at the loop-block's location
            push last spawned entity direction from event-location to last spawned entity with force 1
