Hi, I have some shading errors, shaders seem to be set to Godot3.:
"SHADER ERROR: DEPTH_TEXTURE has been removed in favor of using hint_depth_texture with a uniform. To continue with minimal code changes add 'uniform sampler2D DEPTH_TEXTURE : hint_depth_texture, filter_linear_mipmap;' near the top of your shader."
and I think the crosshair is a little off, the projectile should go closer to the mark.
