Additionally, the character " / " in this application generally indicates that the preceding and following related objects have an "or" relationship.
[0023] The terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments described herein can be implemented in a sequence other than that illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or modules is not necessarily limited to those steps or modules explicitly listed, but may include other steps or modules not explicitly listed or inherent to such processes, methods, products, or apparatus.
[0024] In UE4, created characters can mimic real people to perform various actions, including virtual driving, virtual rowing, virtual flight, and virtual soccer. These actions are composed of multiple independent behaviors, each requiring a separate technological framework. While many action construction technologies are now quite mature, some still face significant technological barriers. Currently, simulating anti-aircraft missile target locking in UE4 remains a challenging problem.
[0025] Therefore, this application provides a simulation method for anti-aircraft missile target locking, which is used to simulate anti-aircraft missile target locking, such as... Figure 1 As shown, the anti-aircraft missile can be the Qianwei-2. The method includes:
[0026] S110. When the target enters the range of the preset collision ball, the target is stored in the array Items.
[0027] When a target enters the range of a preset collision ball, the target is stored in the array Items.
[0028] It should be noted that before the target enters the firing range, a collision sphere with a radius of X meters can be added to the center of the anti-aircraft missile model. (X is the missile's range, X>0).
[0029] When a target enters the range of this collision ball, it is stored in the array Items;
[0030] When a target leaves the range of this collision ball, remove it from the Items array.
[0031] S120. When there is a target in the array Items, a new array ItemsB is created to store the targetable targets and the following steps are performed.
[0032] When a target exists in the array Items, a new array ItemsB is created to store the targetable targets, and steps one through three are executed.
[0033] S130, Step 1: If the target being locked exists, then the locked target is the final locked target being searched for, and this frame logic ends; if the target being locked does not exist, then proceed to Step 2.
[0034] Step 1: If the target being locked exists, then the locked target is the final locked target being searched for, and this frame logic ends; if the target being locked does not exist, then proceed to Step 2.
[0035] S140, Step 2: If the target being targeted exists, start timing. When the timer reaches N seconds, set the target being targeted as the final locked target, and this frame logic ends.
[0036] Step 2: If the target being targeted exists, start timing. When the timer reaches N seconds, set the target being targeted as the final locked target, and this frame logic ends.
[0037] It is worth noting that if the target being aimed at leaves the aiming range during the timing process, the timer is reset to zero, the target being aimed at is set to empty, and step three is executed; if the target being aimed at does not exist, step three is executed.
[0038] S150, Step 3: Clear array ItemsB, traverse array Items, if a target enters the aiming range, add the target to array ItemsB; if there is at least one target in array ItemsB, determine the final locked target from the at least one target, and clear the timer, and this frame logic ends.
[0039] Step 3: Clear array ItemsB, iterate through array Items, if a target enters the aiming range, add the target to array ItemsB; if there is at least one target in array ItemsB, determine the final locked target from the at least one target, and clear the timer, and this frame logic ends.
[0040] Understandably, in step three, the method also includes:
[0041] If there is no target in array ItemsB, the logic of this frame ends; if there is at least one target in array ItemsB, then determining the final locked target from the at least one target specifically includes: if there is only one target in array ItemsB, then that one target is determined as the final locked target; if there are at least two targets in array ItemsB, then the target closest to the anti-aircraft missile is set as the final locked target.
[0042] It should be added that the simulation method for anti-aircraft missile target locking provided in this application can also determine whether the target has entered the aiming range. Please see [link to application]. Figure 3 The aiming range provided in this application can be a cone.
[0043] The apex of the cone represents the center of the missile sight, and angle 'a' is the aiming angle, which defaults to 5 degrees and can be changed.
[0044] Among them, the three-dimensional coordinates of the anti-aircraft missile pointing at the target are V4 = V1 - V2, where the three-dimensional coordinates of the target's location are V1 and the three-dimensional coordinates of the anti-aircraft missile's location are V2.
[0045] The angle between V4 and V3 is b, where the forward direction of the anti-aircraft missile sight is V3;
[0046] If angle b ≤ a, then the target is within the aiming range. Otherwise, the target is outside the aiming range.
[0047] This application provides a simulation method, device, and storage medium for anti-aircraft missile target locking. The method includes: when a target enters the range of a preset collision ball, storing the target in an array Items; when a target exists in array Items, creating a new array ItemsB to store targetable targets, and executing the following steps: Step 1: If a target being locked exists, the locked target is the final target to be locked, and this frame logic ends; if the target being locked does not exist, proceed to Step 2; Step 2: If a target being aimed exists, start a timer; when the timer reaches N seconds, set the target being aimed as the final target to be locked, and this frame logic ends; Step 3: Clear array ItemsB, traverse array Items, if a target enters the aiming range, add the target to array ItemsB; if at least one target exists in array ItemsB, determine the final target to be locked from the at least one target, and reset the timer, and this frame logic ends. This method enables the simulation of anti-aircraft missile target locking.

[0050] The second processing module 202 is used to create a new array ItemsB to store targetable targets when there are targets in the array Items, and to perform the following steps:

When the timer reaches N seconds, set the target being aimed at as the final target to be locked, and this frame logic ends; Step 3: Clear array ItemsB, traverse array Items. If a target enters the aiming range, add the target to array ItemsB; if there is at least one target in array ItemsB, determine the final target to be locked from the at least one target, and reset the timer to zero, and this frame logic ends.
[0052] Furthermore, the second processing module 202 is specifically used to: if the target being targeted leaves the aiming range during the timing process, the timing is reset to zero, the target being targeted is set to empty, and step three is executed; if the target being targeted does not exist, step three is executed.
[0053] Furthermore, the second processing module 202 is specifically used for: if there is no target in array ItemsB, then the logic of this frame ends; if there is at least one target in array ItemsB, then determining the final locked target from the at least one target specifically includes: if there is only one target in array ItemsB, then determining the one target as the final locked target; if there are at least two targets in array ItemsB, then setting the target closest to the anti-aircraft missile as the final locked target.
