I am trying to change the color of the face on a CC3MeshNode. I am retrieving the selected face data with the below code.
CC3MeshNode*node = (CC3MeshNode*)aNode;
CC3MeshIntersection myMeshIntersection[kMeshHitCountMax];
CC3Ray touchRay = [self.activeCamera unprojectPoint:touchPoint];
CC3Ray localRay = [aNode.globalTransformMatrixInverted transformRay:touchRay];
[node findFirst:kMeshHitCountMax intersections:myMeshIntersection ofLocalRay:localRay acceptBackFaces:NO acceptBehindRay:NO];
CC3FaceIndices indices = [node faceIndicesAt:myMeshIntersection[0].faceIndex];
Ive tried to change the VertexColor but it doesn't change anything.
ccColor4F color = ccc4f(255, 0, 0, 255);
for (int i = 0; i < 3; i++) {
[node setVertexColor4F:color at:indices.vertices[i]];
}
Nothing happens.
Actually, I changed the vertex color on a object in Maya and I didn't get what I was looking for. I'm actually not sure if changing the VertexColor would be what I should be doing. I want to achieve something like this:
I'm new to the whole 3d thing, can someone shine a light on a solution?
-Thanks for your time. :)
EDIT
I got the above code working, I was just forgetting to update the Buffers
[node updateGLBuffers];
but it wasn't what I was going after.
Can someone point me in the general direction of what to look up so that I highlight the selected face?

Right now I am having issues updating the dimensions/materials of walls.
The A-Scene in question is one that i am hosting(not hosted on 3d.io website/platform) that was obtained via uploading a 2d floorplan.
Here is a snippet from my code. Basically, this snippet appears to be updating the data of the walls effectively, changing the height to 1 meter. But, the changes are not being reflected visually.
let walls = document.querySelectorAll('[io3d-wall]')
for(let i = 0; i<walls.length; i ++){
walls[i].components['io3d-wall'].data.h = 1
walls[i].components['io3d-wall'].update()
}
If you have any notions as to why I am experiencing this issue please share.
Thank You

Blockvue
use standard A-frame syntax
let walls = document.querySelectorAll('[io3d-wall]')
for(let i = 0; i<walls.length; i ++){
walls[i].setAttribute('io3d-wall', {h: 1})
}
Okay so I am making one of those scrolling shooter Galaga-type game using Game Maker Studio. I created the first enemy and set up a spawner for them. They are supposed to just fly downwards towards your ship. That worked fine. But when I made the 2nd enemy, I wanted to make it move more slowly and side-to-side. I also wanted to make them bounce off the edges of the screen. But it just won't work. I can't figure what the hell the problem is and it it driving me insane. If anyone has any ideas, please, share them with me. If you need any more info on the game i can provide it. Here is the code for the step event of the 2nd enemy:
// Control the enemy
if (y > room_height+16)
{
instance_destroy();
}
// Die code
if (armor <= 0)
{
instance_create(x, y, o_explosion_center);
instance_destroy();
}
// Bounce off edges
if (x >= room_width-16)
{
hspeed = -1;
}
if (x < 16)
{
hspeed = 1;
}
First of all, you didn't say what wasn't working. The code you posted is correct, everything depends on the expected result.
One issue I can see id if this code is used by the two enemies. You want them to have different speeds, but once they bounce, their horizontal speeds will be 1 because you set hspeed to 1 and -1. When you create them, you should set a move_speed variable, and for the bouncing, write in the step event :
hspeed = -1*move_speed //instead of hspeed = -1
and
hspeed = move_speed //instead of hspeed = 1
This way, they will keep their initial speeds.
For more help, could you please explain what doesn't work and post the creation code ?
I'm new to GameMaker, and to making games, for my second game ever I was just going to use GameMakers built in physics. It's a RPG and I'm having lot's of trouble getting the guy to shoot the bullet. I can get the bullet to be placed in the room and at the angle it needs to be at. You could normally then just use the objectnamehere.speed = to what ever you want your speed to be. But! using physics you could use the phy.speed but that's a read only variable. So i half to use the phy_speed_x and phy_speed_y. But how do I get it to shoot in the direction the bullet object is? Here's the code I have so far.
// Player shoot
var shootButton = mouse_check_button_pressed(mb_left);
var bulletSpeed = 10;
if (shootButton) {
bullet = instance_create(ot_player.x, ot_player.y, ot_bullet);
bullet.phy_rotation = phy_rotation;
bullet.phy_speed_x = bulletSpeed;
bullet.phy_speed_y = bulletSpeed;
}
I have tried putting many different variables where I have the bulletSpeed variables but nothing has seem to work. I'm stuck here, I've watch tutorials and read lots of stuff but nothing has worked!
I figured it out.
var shootButton = mouse_check_button_pressed(mb_left);
var bulletSpeed = 10;
if (shootButton) {
bullet = instance_create(ot_player.x, ot_player.y, ot_bullet);
with(bullet) {
phy_rotation = other.phy_rotation;
ldx = lengthdir_x(15, -phy_rotation)
ldy = lengthdir_y(15, -phy_rotation)
physics_apply_impulse(x, y, ldx, ldy);
}
}
I feel really dumb for having to post this, but I've been trying to achieve this for an entire week now and I'm getting nowhere!
I'm trying to create a highscore board. Top 10 scores, saved to an INI file. I have searched every single thing on the entire internet ever. I just do not get it.
So what I have tried is this...
I have a "load_room" setup. When this room loads, it runs this code:
ini_open('score.ini')
ini_write_real("Save","highscore_value(1)",highscore_value(1));
ini_write_string("Save","highscore_name(1)",highscore_name(1));
ini_close();
room_goto(room0);
Then when my character dies:
myName = get_string("Enter your name for the highscore list: ","Player1"); //if they enter nothing, "Player1" will get put on the list
highscore_add(myName,score);
ini_open('score.ini')
value1=ini_write_real("Save","highscore_value(1)",0);
name1=ini_write_string("Save","highscore_name(1)","n/a");
ini_close();
highscore_clear();
highscore_add(myName,score);
score = 0;
game_restart();
I'm not worried about including the code to display the scores as I'm checking the score.ini that the game creates for the real values added.
With this, I seem to be able to save ONE score, and that's all. I need to save 10. Again, I'm sorry for asking the same age-old question, but I'm really in need of help and hoping someone out there can assist!
Thanks so much,
Lee.
Why you use save in load_room instead load?
Why you clear the table after die?
You need to use loop for save each result.
For example, loading:
highscore_clear();
ini_open("score.ini");
for (var i=1; i<=10; i++)
{
var name = ini_read_string("Save", "name" + string(i), "");
var value = ini_read_real("Save", "value" + string(i), 0);
if value != 0
highscore_add(name, value);
}
ini_close();
room_goto(room0);
Die:
myName = get_string("Enter your name for the highscore list: ","Player1");
highscore_add(myName, score);
ini_open("score.ini");
for (var i=1; i<=10; i++)
{
ini_write_string("Save", "name" + string(i), highscore_name(i));
ini_write_string("Save", "value" + string(i), string(highscore_value(i)));
}
ini_close();
score = 0;
game_restart();
And few more things...
score = 0;
You need do it when game starts, so here it is unnecessary.
get_string("Enter your name for the highscore list: ","Player1");
Did you read note in help?
NOTE: THIS FUNCTION IS FOR DEBUG USE ONLY. Should you require this functionality in your final game, please use get_string_async.
I used ini_write_string(..., ..., string(...)); instead ini_write_real() because second case will save something like 1000.000000000, and first case will save just 1000.
I've ran into a weird problem with getCharBoundaries, I could not figure out what coordinate space the coordinates returned from the function was in. What ever I tried I could not get it to match up with what I expected.
So I made a new project and and added simple code to highlight the last charater in a textfield, and all of a sudden it worked fine. I then tried to copy over the TextField that had been causing me problems, into the new project. And now the same weird offset appeared 50px on the x axis. Everything else was spot on.
So after some headscracthing comparing the two TextFields, I simply can not see a difference in their properties or transformation.
So I was hoping that someone might now what property might affect the coordinates returned by getCharBoundaries.
I am using Flash CS4.
I've just had exactly the same problem and thought I'd help out by offering what my findings are. With a help from this thread, I tried to find everything that wasn't 'default' about the textfield I was using. I found that when I had switched my TextFormatAlign (or 'align' in the IDE) and TextFieldAutoSize properties to 'LEFT' as opposed to 'CENTER', it solved the problem.
A little late in the game perhaps, but worth knowing for anyone running into the same problem. This was the only thread I could find that raised the right flag...
Well the getCharBoundaries returns the boundaries in the textfield coordinate system. Where the origin is topleft corner of the textfield.
getCharBoundaries does not take into consideration the scrolling. you need to check if there are scrollbars on its parent (textarea) and if so relocate. One quick way of doing it is using localtoglobal and globaltolocal. Use the first to translate from the textfield coordinate system to the application coordinate system and then use the second to translate from the app coordinate system to the coordinate system of the parent of the textfield which is the textarea. I'm fine tuning a my method to get char boundaries i will publish it today on my blog

Works For Me(tm) (Flex Builder AS3 project):

stage.scaleMode = 'noScale';

To literally answer your question, it returns the coordinates in the TextField's coordinate system, not it's parent, and it is affected by DisplayObject.transform.matrix, which is the backing for the .x, .y, .scaleX, .scaleY, .width, .height, and .rotation properties.
What ever it was the solution was simple to add a new TextField, never found out what property screwed everything up.
The first answer is correct in most cases. However if your field is parented to another movie clip it may still return the wrong y coordinate. try this code:
//if this doesn't work:
myTextFormat = new TextFormat();
myTextFormat.align = TextFormatAlign.LEFT;
myFieldsParent.myField.autoSize = TextFieldAutoSize.LEFT;
myFieldsParent.myField.setTextFormat( myTextFormat);
//try this:
var x = myFieldsParent.myField.getCharBoundaries(o).x;
var y = myFieldsParent.myField.getCharBoundaries(o).y;
var myPoint:Point = new Point(myField.getCharBoundaries(o).x,myField.getCharBoundaries(o).y);
var pt:Point = new Point(myFieldsParent.myField.getCharBoundaries(o).x, myFieldsParent.myField.getCharBoundaries(o).y);
pt = myFieldsParent.myField.localToGlobal(pt);
//pt is the variable containing the coordinates of the char in the stage's coordinate space. You may still need to offset it with a fixed value but it should be constant.
I didn't test this code as I have adapted this example from code that is embedded into my project so I apologize if I'm missing something...
