Ah sorry, forgot you're using C-script instead of Lite-C  First of all:
entity ghostobject
{
flags = TRANSLUCENT;
alpha = 30;
}
This creates a view entity, but you want a "normal" entity , not a view entity, so replace that code with this: Change the while condition ( "while(isplaceobject == NULL)" ) to "while(isplaceobject != 0)", as it's a variable, not a pointer, and set this variable to something else than 0 before entering the while loop - this way you can always cancel the loop by setting the global variable to 0 anywhere in your code. In this code:
if(mouse_left)
{
ent_create("crate.mdl",target,null);
if(ghostobject == NULL)
{
ent_remove(ghostobject);
isplaceobject = 0;
}
}
You need to change the nested if-condition to "ghostobject != NULL". And now a very important part:
if(ghostobject == NULL)
{
ghostobject = ent_create("crate.mdl",target,NULL);
}
else
{
vec_set(ghostobject.x,target);
}
You need to change it to this:
if(ghostobject == NULL)
{
ghostobject = ent_create("crate.mdl",target,NULL);
ghostobject.transparent = on;
ghostobject.passable = on;
ghostobject.alpha = 30;
}
else
{
vec_set(ghostobject.x,target);
}
You really need to make it passable in order to let the trace ignore the ghostobject. Tell me if it's still not working

Here is it:
entity* ghostobject;
var isplaceobject = 1;
function spawn()
{
while(isplaceobject != 0)
{
temp.x = mouse_pos.x;
temp.y = mouse_pos.y;
temp.z = 0;
vec_set(target,temp);
target.z = 10000;
vec_for_screen(temp,view_build);
vec_for_screen(target,view_build);
if(c_trace(temp,target,IGNORE_ME | IGNORE_PASSABLE) > 0)
{
if(mouse_left)
{
ent_create("crate.mdl",target,null);
if(ghostobject != NULL)
{
ent_remove(ghostobject);
isplaceobject = 0;
}
}
if(ghostobject == NULL)
{
ghostobject = ent_create("crate.mdl",target,NULL);
ghostobject.transparent = on;
ghostobject.passable = on;
ghostobject.alpha = 30;
}
else
{
vec_set(ghostobject.x,target);
}
wait(1);
}
}
}
That only works once... then the ghost disappears and you cant spawn another crate.

You need to set isplaceobject to 1 inside the function Otherwise it will remain 0, and the code in the loop will never be reached anymore, as the while-condition will then be false.

var isplaceobject;
function spawn()
{
isplaceobject = 1;
while(...)
{
... // other code
You also need to move the "wait(1);" outside the if-branching, as it will otherwise produce a crash if the trace hits nothing or hits an object from the inside. I don't know why you're getting more than 1 cubes, maybe you're calling the function more than once at the same time? Also add a break; or return; here:
if(ghostobject != NULL)
{
ent_remove(ghostobject);
isplaceobject = 0;
return;
}

Here is my code once more.
entity* ghostobject;
var isplaceobject;
function spawn()
{
isplaceobject = 1;
while(isplaceobject != 0)
{
temp.x = mouse_pos.x;
temp.y = mouse_pos.y;
temp.z = 0;
vec_set(target,temp);
target.z = 10000;
vec_for_screen(temp,view_build);
vec_for_screen(target,view_build);
if(c_trace(temp,target,IGNORE_ME | IGNORE_PASSABLE) > 0)
{
if(mouse_left)
{
ent_create("crate.mdl",target,null);
if(ghostobject != NULL)
{
ent_remove(ghostobject);
isplaceobject = 0;
return;
}
}
if(ghostobject == NULL)
{
ghostobject = ent_create("crate.mdl",target,NULL);
ghostobject.transparent = on;
ghostobject.passable = on;
ghostobject.alpha = 30;
}
else
{
vec_set(ghostobject.x,target);
}
}
wait(1);
}
}
The problem is coming from when i hold down the left mouse buttons they just keep spawning in a huge line all the way up to the camera, then the engine crashes due to too many entities. Is there a way where even if i hold the left mouse button down it will only run that if statement once? Also im running the function by putting spawn(); in another function.
