Fluttering aim target [Solved]

[chainsawpenguin]

Hey, guys! I'm having a weird issue: my target flutters when I'm very close to an NPC (if, for example, I'm trying to target his head from very short range).

Here's what's happening:

- The aim target is "fluttering" from one point to another, rather than staying locked in the middle of the screen
- The NPC DOES have a ragdoll, with the BodyPart layer on all of the bones, and the Enemy layer on everything else on the NPC
- The players damage layers are "Default, BodyPart"

The most frustrating part is that if I put a target EXACTLY on the NPCs head, and pull the trigger, it doesn't register as a hit. If I adjust my aim so that my AIMTARGET is off in the distance but I can mentally draw a line from the gun to the aimtarget that would pass through the head (or turn on the Laser sight), the hit registers.

How do I make the aiming reticle move to where the bullet is going to go when I pull the trigger? 

As near as I can tell, the variables of "isValid" and "validPoint" are ALWAYS true (except for the first frame, because the default for isValid is false, but thereafter it's set to the value of validPoint, which is defaulted to true).

I can't see any ciircumstances in the code where these are 1 - not set to true and 2 - change the position of the aiming reticle.

In more direct terms, I guess, I could ask this very specific question:

Where does SimpleAimGroupe/AimTarget/valid/AimCenter's POSITION get updated, and HOW does that correspond to the projectile's anticipated final destination?


I guess what I'm looking for is the GTA V/Red Dead Redemption II model: a fixed dot in the middle of the screen, and a raycast from the middle of the screen to any colliders. If the raycast hits, the shot hits, and the animation and projectile reflect that. I just really don't want my AIMTARGET to move around on the screen, but it's not clear how I'd disable that in the Shooter Template...

I can send you my project if you want to see what I'm going on about, OR could I respectfully request a demo scene of the desired behavior, maybe?

Since the bullet instantiate from the muzzle of the weapon, we created a crosshair assistance to visually help the player to see where the bullet will hit (similar to what some games do, like MGSV)

You can disable that in the AimCanvas, for example, the AimID2 (AssaultRifle) we have the AimCenter which is the little dot that is always in the center of screen and the AimTarget object which will align to display where the shot will actually hit.

You can disable the AimTarget to have only the crosshair in the center of the screen, but this doesn't mean that the bullet will go there, because as I mentioned it instantiates from muzzle of the weapon instead of the Camera center as of some games do.

Well that just makes eleven kinds of sense! THANKS for the clarification!!

UPDATE: Just so that I can remember this when I'm looking around to solve this in the future: RaycastAimTarget.

If it is OFF in either the PLAYER or the WEAPON (it's in the IK tab), then the aim behavior mimics MGSV, with a fixed AimCenter, and a floating AimTarget, which will help the player visualize the bullet path from the gun to the AimTarget to the AimCenter.

If it is ON in both the PLAYER and the WEAPON, the weapon aim will be locked to the center of the camera view, which is a more old-school style, but much more what I was looking for (and, hey, I'm old).

There's one outstanding thing: when I'm using the latter option, and I'm very close to an object, my IK tries to go to where the camera is, resulting in some funky aiming angles. If I'm very VERY close to an object, I can't shoot at it at all, and the AimCanvas displays a red "X". I think that merely expanding the range of the "invalid" zone would eliminate the weird "IK trying to get to the cam's position" issue.

Any ideas on where I can change that value?

Also, this thing is EXCELLENT! I keep showing it off at work, using models from Synty, and everyone agrees that it's VERY cool!

Thanks for the support and feedback!

You can customize the Min Distance to Aim (shooterManager) value and the AimReference (weapon itself)
to have more precise adjusts for your character/weapon
