hi.. im a newbie here. currently im developing an interior design game using lite-c.
i've found an example and make it as reference for my game. i manage to get the item placed on the scene. and now, i want to make price for each item(entity) and total up them at the end. the price will be add for each item dragged into the
scene and subtracted when the user delete the item from the scene.

the case is, i wrote the code to call the item like this :

#define f(furniture.pstring)

TEXT* furniture ={
strings = 25;
string("nullunit.mdl","sofa.mdl","tv.mdl");
}
.
.
.

and called by this function:

.
.
.

if(mouse_left){
{
unit = ent_create(f[my.skill2],my.x,act);
vec_set(unit.pan,my.pan);
}
.
.
.


but i had no idea how to combine the price for each item and call it after that to add or substract the related price, and total them up.
does anyone has any idea how to do it?


**sorry for my bad english

You will need a var that will keep track of the total price, and then you add or subtract from that var to have a correct total as you add or remove items from display. So

if(mouse_left){
{
unit = ent_create(f[my.skill2],my.x,act);
vec_set(unit.pan,my.pan);
grandtotal += price_of_f[my.skill2];
}
if(mouse_right){//also make sure this only works when over an entity.
ent_remove(blah blah)
grandtotal -= price_of_f(blah blah);
}

Another option is to create a manager that knew every item in the screen and have it add up a total each cycle. This one could be buggy if not done right but could be more simple depending.

tq so much foxhound. it gave me some idea.


another question, how am i suppose to embed each price to each item?
is it i need to put it in the same TEXT field?

Putting it in the text field would display the the price but would not do anything to keeping track of how much is spent. You're best bet is to make a struct for the furniture and having an int to keep track of the price and have it added in the function that creates the furniture and places it in the level.

owh ok..!! thanks~

surely you could just save the price in one of the entities skills?

#define cost skill1
action unit(){
my.cost = 15;
}

or just create an array to match your TEXT



*untested* brackets may be missing

hope this helps

mrguest, thank you so much. i guess it helps a lot. though i have'nt do it. hehe..
i will try it after this.

i manage to get the item on the scene, as you know, interior design should can place item onto other item. but i couldnt place other item onto another item cause of the bounding box. for example, a telephone on the table. do you know how to fix this?

use 'c_setminmax(entity)' to set the bounding box to the actual size of the model.

djbmaster, i did use c_setminmax..
any other option besides c_setminmax?

anyone knows why cant i place an item onto another item? is it really because of the bounding box or lite c does not support placing item onto other item except terrain?

if it is, how can i fix this?


also want to ask, how to rotate a camera while it points to fix view?
