Hi Folks
Recently I dig into a "laser beam" kinda effect and found a short tutorial:
and works fine... The "beam" colides with the CollisionShape2D in the StaticBody2D
Well, the thing is, when I put the LaserBeam scene into the game, it doesn't colide with other objects (the enemy in this image has an area2D with a colisionshape):
how can I handle this colisions? Thanks
If I had to guess, the problem is that the raycast cannot detect the Area2D node. If you set collide_with_areas (documentation) to true on the Raycast2D, then that should hopefully fix the problem.
Amazing... thank you! <3
And can I choose with areas colide is active? I use to group areas with, hummm... for instance: add_to_group("ship") add_to_group("enemy_simple") add_to_group("enemy_bullet")
and with this collision, emiting signals or trigger some function? I know hot to do with "bullets" made of Area2D(+CollisionPolygon2D, etc), but I still really lost working with raycast
If you are using a Raycast2D node, you can put the bullets on a different collision layer/mask than the Raycast2D (or vise versa) and the Raycast2D node should ignore them. I'm not sure if there is a built-in way to have a Raycast2D node ignore a group. You can add each node in the group as an exception and then call add_exception (documentation) but it will not react to new nodes added to the group unless you call add_exception again.
Excellent idea! Thank you very much
var enemyBullets = get_tree().get_nodes_in_group("enemyBullets")
for i in enemyBullets:
add_exception(i)works like a charm! thanks again
