I’m in trouble. New on learning LUA, and trying do make an ‘RPG’ in defold.
Btw, i learned how to do pixel-art animation to this, but it just do not play while the walk, but when idle.
All the animations groups are separeted, including the idle directions.
Heard about go.animate, but still not sure how to use it.
What should I do?
following lua used ::
if self.direction.y > 0 then
msg.post('#sean','play_animation',{id = hash('back_walk')})
elseif self.direction.y < 0 then
msg.post('#sean','play_animation',{id = hash('front_walk')})
end
if self.direction.x > 0 then
msg.post('#sean','play_animation', {id = hash('right_walk')})
elseif self.direction.x < 0 then
msg.post('#sean','play_animation',{id = hash('left_walk')})
end
didn’t understand …
i mean, undertood the logic behind, but when i execute the ‘debug’ tool points to me an error, even it’s working exactly what i wanted
i found where its the error, but … (?)
in “” local anim = hash(‘idle’) “”" doesn’t recognizes any texture, and then stop the walking animation to idle form, in exactly direction
I’m not entirely sure I understand what problem you are running into. What is the error you are getting? Do you have an animation/image in your atlas that is named “idle”?
I have 4, to all four directions. (and trying to make for all… )
In this case i was trying to use the front-looking, but the error dont recognizes for some reason
Evan removing the others , its the same
actually i’ll remake this part of script. Almost certain i messed up with some abreviation or invalid name …
“”" Unable to play animation ‘idle_front’ from texture ‘/_generated_c28d3bec.texturec’ since it could not be found. “”"
this is the error message, but when i was checking my animations name… i’ve change the order from words… a dumb mistake, i know ( from ‘front_idle’ to ‘idle_front’)
anyway, this don’t fully solve my problem. ( but i can just ignore it, too )
yeah, it’s working as well, but what i need is the character face te direction when stop walking
I tried the ‘on_reload’ and ‘final’ functions, but not sure how use, and doesnt work so i just deleted
the functions with nothing i deleted from message
function init(self)
msg.post(".", "acquire_input_focus")
self.speed = 3
self.direction = vmath.vector3()
self.current_anim = nil
end
function update(self, dt)
if vmath.length_sqr(self.direction) > 1 then
self.dir = vmath.normalize(self.direction)
end
local new_position = go.get_position()
go.set_position(new_position + self.direction * self.speed)
local anim = hash('front_idle')
---Animate by direction
if self.direction.y > 0 then
anim = hash('front_walk')
elseif self.direction.y < 0 then
anim = hash('back_walk')
elseif self.direction.x > 0 then
anim = hash('right_walk')
elseif self.direction.x < 0 then
anim = hash('left_walk')
end
if anim ~= self.current_anim then
msg.post("#sean", "play_animation", { id = anim })
self.current_anim = anim
end
self.direction = vmath.vector3()
end
function on_input(self, action_id, action)
--movement
if action_id == hash('move_up') then
self.direction.y = 1
elseif action_id == hash('move_down') then
self.direction.y = -1
end
if action_id == hash('move_right') then
self.direction.x = 1
elseif action_id == hash('move_left') then
self.direction.x = -1
end
end
Thank you for sharing the script! So, you need to somehow keep track of the direction you were moving in the last frame and use this information to display the correct idle animation when the player is no longer moving (ie when self.direction.x and y is 0).
Let’s break this up:
Keep track of direction
I suggest that you create a new variable previous_direction in init()
function init(self)
...
self.direction = vmath.vector3()
self.previous_direction = vmath.vector3()
end
At the end of the update() function you update previous_direction:
function update(self, dt)
...
self.previous_direction = self.direction
self.direction = vmath.vector3()
end
Use the previous direction to set idle animation if not moving
Let’s modify your update function where you animate based on direction. If self.direction.x and y is 0 we instead use self.previous_direction to play an idle animation:
if self.direction.y > 0 then
anim = hash('front_walk')
elseif self.direction.y < 0 then
anim = hash('back_walk')
elseif self.direction.x > 0 then
anim = hash('right_walk')
elseif self.direction.x < 0 then
anim = hash('left_walk')
else
-- no movement, play idle animation!
if self.previous_direction.y > 0 then
anim = hash('front_idle')
elseif self.previous_direction.y < 0 then
anim = hash('back_idle')
elseif self.previous_direction.x > 0 then
anim = hash('right_idle')
elseif self.previous_direction.x < 0 then
anim = hash('left_idle')
end
end
I’m not sure why that is. If you want to figure it out you need to do some debugging. Here’s a manual page about debugging game logic to get you started:
