I am in the middle of coding a system to make a platformer with slope detection.
The characters were saved as char.scn and instantiated to a “stage” where they interact with objects.
Then, I shot 9 rays in different positions on the fixed_process function to start the magic and also created 9 lines for the rays for a visual representation on the _draw function.
var raycast_step = 320
space_state = get_world_2d().get_direct_space_state()
var raycast_step_multiplier = 5
ray bottom_right:
bottom_right = space_state.intersect_ray(get_corner("bottom_right"), get_corner("bottom_right") + Vector2(raycast_step_multiplier*raycast_step,0), [self] )
func draw_lines():
if main._debug:
#bottom_right
draw_line(get_corner("bottom_right"), get_corner("bottom_right") + Vector2(raycast_step_multiplier*raycast_step,0),Color(50,0,0),1.0)
get_corner function:
func get_corner(corner):
var corners = {
top_left = get_node("top_left").get_pos()+Vector2(skin,skin),
top_right = get_node("top_right").get_pos() +Vector2(-skin,skin),
bottom_left = get_node("bottom_left").get_pos()+Vector2(skin,-skin),
bottom_right = get_node("bottom_right").get_pos()+Vector2(-skin,-skin)
}
if corner == null:
return corners
else:
return corners[corner]
When I checked for hits by printing the dictionary that results from:
the bottom_right var, I got nothing at all. This would test for collisions on the bottom-right side of the object.
After a lot of tries to pimpoint what was wrong in my code I decided to put an obstacle at the top of the screen to see if the position for the rays weren’t using the node’s position wrongly and finally I discovered that somehow, even though I used the same position code to shot the ray and also to draw the line, somehow the rays are messed-up while the lines draw are ok, even following the character.
So, what am I doing wrong? Why are the lines drawn ok but the raycast is not being shot from the right position(coming and following the character)?
