[1.12.2] Detecting obstacle in entity path

[fcelon]

Hello,

I would like to improve creepers a little by giving them ability to blow up obstacles in their path. I siplmy want them t blow up if there are some blocks in the way preventing them from reaching the player. However, I don't know how to detect that.

Thanks for any help.

It would be kind of tricky because path finding works around the blocks, so in a sense there is never a block in the path. Now if you mean to blow things up in a straight line to the target player, that is possible. Just ray trace along the vector between the creeper and the target and blow things up along the way. However I have made a similar entity in the past and it is really over powered and not as much fun as it sounds. But go ahead and try it.
