Hey,

Well i have a question. Title pretty much sums it up, but what im trying to do is to create a traceline for a, what you could almost call, FPS game now when version 1.2 is out. The camera itself is locked, so you cant turn, or move, but the mouse is free. So i have to, when shooting on targets, track the position of mouse, and when its over a unit -> set that unit in a unit varaible. Much like any other traceline, but i really dont have any experiance with mouse tracking and how it would work with the unit, since the units distance from the camera may differ from different situations.

I do have a unit, which is hidden, at the location of the camera.

Would appreciate help, on a quite low level, since i may not know the new functions that well!

Thanks in advance

PS: Just to clearify - The yaw of the camera is not movable, so ONLY the mouse can be moved.

Are you concerned with network traffic, or do you intend for this to be a one-player map?

If the latter, you could use the new 'Mouse Moved' event to move a global point variable to the position of the player's mouse, and perform any math from the point of the camera to the point at the mouse (i.e. "Distance Between Points" or "Angle Between Points").

I'm not entirely sure what you're asking, but I hope this is helpful in some way.

hmm... well...
It made me atleast thinking...

If i do that, save the position of the mouse into a varaible... then do a "player click left mouse (trigger: shoot) then save the position of the unit closest to point of mouse... the somehow do a if then else, with condition Angle between Mouse point and camera VS Unit point and camera =< 1.. then also have a hight check... "hight of unit < mouse Z location.. then maybe it would work...

But since theres sadly no condition i can do this with then i cant.

Roy thats anyway, allwas appreciate the responses.

What im trying to do is this:

Okay, so this is a trigger I wrote which I think will make a point move like a bullet flying in the direction of a clicked mouse.



The local variables find all the needed data to make the calculations, such as finding the slope of the line.
The while loop follows the path of the line, and stops either when it finds a unit, reaches a certain distance, or hits the ground.
If a unit is found, that unit is killed.

I assumed P1 to be the shooter and P2 to be the units that P1 is shooting. I'm not sure if this works in the way I'm imagining, though.

Thats what i did, but it doesnt work. It gives the error:

Trigger Error in Get_Shoot2_func;
could not get "p" from perameter in
'pointgetheight' (value: 0)

Ah, it is actually a problem with the code I wrote. You're trying to get the height of "Bullet" when it is not set to a given point.

Set Bullet to be the same position and same height as the camera's point before the while loop.

And for formatting the trigger text, the easiest way is to use the [pre] tag.

Still the same issue mr Roy.

(this is just your trigger rendered, not a fix )

I saw that you use two times the condition "(PlayerUnit[(Triggering player)] is alive) == true". Why that?

Change the default of the Bullet local variable.



(It's "Point From XYZ")

Im sorry for being such an freelancer, i allwas do it all bymyself, but i really cant get it working. I sent this.
The map is just a test to get it working and ignore layout, and .. basicly everything.
The trigger = shoot2

"Hold "F" to jump up
*Release "F" to cover
*Click left mouse to shoot

Only 1 unit. He wont do any harm, but if you sucessfully shoot him he will back start fleeing

Sooooooooooooooooooooooooooooooooooooooooooooo borring, but i made it way to easy instead.

Event: Unit clicked
Action: Create damage on unit from unit

......
So what im now instead trying to do is to create the model "ghost impact" at the location i click.

"Event: mouse clicked"
Action: Create effect, or actor, or what ever, at point Mouse click x,y,z.

How to create such an actor, or effect?

PS: 2 things:
1. Im sorry im pstin this dataeditorial question here now.
2. im sorry i didnt forfill the trigger you created roy, but since the impact is direct, and no projectile has to be directed from camera view to unit, i made it easy (just didnt think of it before)

what i mean with my quetion is that i want to create a "bullet hit splash" at point where im shooting (like in the video from above)

I did a few tests and figured out that I had a few misconceptions on how the Z-axis operates for these functions. As it turns out, the mouse clicked events completely disregard the Z-axis position and set the click point to the (X, Y) coordinate of the terrain the mouse clicks.

This means that there really is no direct solution to your problem. The clicked distance is exponentially based on the pitch of the camera, and at a certain point the mouse is being clicked beyond the horizon of the map, yielding a steady, high number. Therefore, using the distance of the click and modifying the model's height to correspond with it is impossible.

Furthermore, there doesn't seem to be a way to get the mouse position relative to the screen, which would be perfect for what you're trying to accomplish.

The reason this is (seemingly) impossible while FPS games are possible is because FPS games can use the camera yaw and pitch to shoot in the direction they are facing, and do not have to rely on clicking position. Your system cannot utilize these camera aspects perfectly because you also have the position of the mouse relative to the screen as a variable to the game's functionality.

(Creating the model is really simple, it's just "Actor - Create Model at Point"; the problem is getting the proper point/height).

Unless you know of a way to get the mouse's position relative to the screen, I don't think this is possible.

Hmm i feared this! Thanks alot roy for all your help!

Regarding the model, there is. Theres a library "at a certain site im not allowed to name" where you detect screen resolution of the player -> you do a math which is based on screen resolution and the relation to where mouse is in comparison with where the image is archored.
But i dont know the math for it, ill figure it out! thanks alot mate!
