Hi guys! I am totally new here, so my problem is probably less than interesting, but I couldn’t find the answer.
I want to use a GUI button to control my Player via messages.
for that I have tried to make a function and it works but not as wanted.
"local function move_left(self)
self.input.x=-1 print(“KFDSK”)* end
function on_message(self, message_id, message, sender)
if message_id==hash(“left”) then move_left(self)*
end* end
function on_input(self, action_id, action)
if action_id == hash(“up”) then*
self.input.y = 1*
elseif action_id == hash(“down”) then*
self.input.y = -1*
elseif action_id == hash(“left”) then*
--self.input.x = -1*
move_left(self)..."*
now, when I press on the keyboard, the “move_left” function works fine, it’s moving the player and prints “KFDSK” as my debug message. But when I press the GUI button, it only prints the debug text but the player character does not move. So it works, but not really works…
just for sure, once again

The ` symbol is under the escape button on keyboard. Don’t confuse with the ’ symbol near the enter key.
And either you copy the text from Word or similar app or you have “smart quotes” enabled on your system that invert first quote making it illegal for program code.
Ok, the code was a a little easier to read, but it seems to be missing the end of the code.
E.g. the on_inputfunction wasn’t complete.
If move_left()is called, and the print is coming out, then the self.input.x=-1 must be set, right?
So, the question is, is the self.input reset somewhere in the script?
Well, funny thing is, I have a qwertz keyboard
But I think I see it now.
just for test
local function move_left(self)
self.input.x=-1
print("KFDSK")
end
function on_message(self, message_id, message, sender)
if message_id==hash("left") then
move_left(self)
end
end
function on_input(self, action_id, action)
if action_id == hash("up") then
self.input.y = 1
elseif action_id == hash("down") then
self.input.y = -1
elseif action_id == hash("left") then
move_left(self)
elseif action_id == hash("right") then
self.input.x = 1
elseif action_id == hash("fire1") then
if self.fire_cooldown1 > 0 then
return
end
msg.post("#fire1", "play_sound")
local offset = vmath.rotate(self.direction, vmath.vector3(150, 0, 0))
factory.create("#fire1Factory", go.get_position() + offset)
self.fire_cooldown1 = 0.12
end
if vmath.length(self.input) > 0 then
self.moving = true
self.dir = vmath.normalize(self.input)
end
end
Let’s get back to your problem. So you’re saying that when moving using the keyboard it works but not while pressing a GUI button (which I assume is sending a message)?
You have not shown your update() function yet and I’m guessing there is something in that function which is causing a problem.
Thank! For now, I see it would better to copy the rest of it as well, maybe it is useful.
function init(self)
msg.post(".", "acquire_input_focus")
self.direction = go.get_rotation()
self.rot = vmath.quat()
-- Base rotations half a lap in each direction
self.rot_left = vmath.quat_rotation_z(3.14159)
self.rot_right = vmath.quat_rotation_z(-3.14159)
self.moving = false
--self.firing1 = false notinuse
self.fire_cooldown1 = 0
--self.thrustLeft=false notinuse
--self.thrustRight=false notinuse
self.input = vmath.vector3()
self.dir = vmath.vector3(0,1,0)
self.speed = 200
end
function final(self)
msg.post(".", "release_input_focus")
end
function update(self, dt)
if self.moving then
local pos = go.get_position()
pos = pos + self.dir * self.speed * dt
go.set_position(pos)
end
self.input.x=0
self.input.y=0
self.moving=false
--self.firing1=false notinuse
self.fire_cooldown1 = self.fire_cooldown1 - dt
end
local function move_left(self)
self.input.x=-1
print("KFDSK")
end
function on_message(self, message_id, message, sender)
if message_id==hash("left") then
move_left(self)
end
end
function on_input(self, action_id, action)
if action_id == hash("up") then
self.input.y = 1
elseif action_id == hash("down") then
self.input.y = -1
elseif action_id == hash("left") then
move_left(self)
elseif action_id == hash("right") then
self.input.x = 1
elseif action_id == hash("fire1") then
if self.fire_cooldown1 > 0 then
return
end
msg.post("#fire1", "play_sound")
local offset = vmath.rotate(self.direction, vmath.vector3(150, 0, 0))
factory.create("#fire1Factory", go.get_position() + offset)
self.fire_cooldown1 = 0.12
end
if vmath.length(self.input) > 0 then
self.moving = true
self.dir = vmath.normalize(self.input)
end
end
By doing this, the character starts moving, but to forward by default. If I press any arrow keys, it starts moving into that direction. So if I press Right, it starts moving right by the Gui button, if I press Down, it moves down.
The same happens if I write it into the function itself.
Because your logic got problems. You are assigning direction on_input with self.dir = vmath.normalize(self.input) but not in on_message. You can find lots of examples about movement on Tutorials
Thank you! By generally revamping some lines, it finally reacts as wanted.
As for the tutorials, thank you. I have already finished them, before I have even started anything, but I just couldn’t apply everything as intended for the first time.
But I will continue to learn and I am really grateful for all of you guys for this help you showed.
Thank you
