Cocos3.6 has been on-line for 3 weeks, whether or not the brand new Floor Shader materials, or the CSM cascade shadow, or the brand new DCC materials system, and the animation state machine! !
I haven’t used any of those options but! ! !
So I’m going to spend 4 days to make a easy sport ! A jare chiken sport, which permits everybody to benefit from the scene and acquire cash in it!
Demo Tackle : Jare‘s World! Free Giveaways!!!
1.0 Scene design
With the thought, the subsequent step is the scene design. There must be a giant moon within the scene to exhibit the reflection of skybox, and with many buildings to point out the ability of CSM, and there must be lots obstacles as effectively! Gamers want to leap to the flooring to gather the cash, the design drawing is as follows!
Character choice
Jare Chiken(Cocos’s PM Director!) is kind of just like the chicks within the design drawing!
DCC materials adaptation
The scene selected the Asian Buildings Assortment kind Noyou on Sketchfab, which has lots buidings within the scene and plenties of obstacles!(CC: Historical Chinese language courtyard Park – Obtain Free 3D mannequin by noyou (@zsm123) [55d8371] – Sketchfab)
With the newest Dcc materials adaptation from Cocos, this scene can exported into Cocos with out further config!.
Then arrange the character and buildings in thescene, and add a full moon skybox.
In contrast with the design drawing, which is kind of comparable!
Lastly, draw a coin with moon in Blender, and adapt it by the Dcc materials, the entire scene is full!
Contemplating that the sport scene has greater than 1 million verts and the terrain is comparatively irregular.
The price of utilizing Bullet+Mesh Collider wll be fairly excessive, so the challenge determined to make use of a plug-in CollisionMaster from the shop (CollisionMaster | Cocos Retailer)
-
It’s just a few tens of KB in dimension
-
The built-in octree is optimized for big scenes
-
Supporting ray detection, which is sufficient to write the logic of consuming moon muffins
2.0 Options Used
CSM Cascading Shadows
When CSM is turned off(proper within the image), the perimeters of the shadow are severely jagged. The reason being the low decision of the shadow map, when sampling the shadow map, a number of completely different vertices pattern the identical pixel, leading to aliasing.
After CSM is turned on, a number of shadow maps are used, advantageous shadow maps are used close to the digital camera, and tough shadow maps are used far-off from the digital camera, which not solely optimizes the shadow impact, but additionally ensures rendering effectivity. This characteristic in 3.6 is souseful!
Animation State Machine
Participant wants to regulate the hen to leap up and down, and there are lots of states to be added. If we merely use skeletal animation, lots codes need to be achieved!
By utilizing the Marionette animation, the primary logic might be handed over to the state machine.
It solely must establish whether or not the character is on the bottom or leaping by a number of easy states, after which the character motion might be switched simply with few codes!
Within the sport, you solely want to change the state by ray detection. When the water floor or the bottom is detected, we are able to inform the present state to the state machine with out further codes!
Water reflection
The water floor materials extends the Commonplace PBR, and provides the UV movement of the Regular Map, and the IBL of the sky field.
The sting of the water is smoothed by AlbedoMap, (will probably be unnatural to regulate the transparency of the sting by SmoothStep)
**My drawing for the water edge! **
Object Detection
Since collisionmaster doesn’t help bodily triggers for colliders, rays can be utilized for object set off detection.
Right here, a ray is emitted from the highest of the pinnacle to the foot. When the grouping of the cash is detected, the gap from the cash can be returned in the results of the ray detection, and numerous logics might be written by the gap.
Bounce Detection
Bounce detection additionally makes use of two rays, the blue one is used for roof collision detection, and the purple one is used for floor collision detection.
When the blue detection distance is just too low, the upward motion velocity of the character is decreased. When the purple detection is near the bottom, the downward motion velocity is decreased, and the animation state is switched to strolling or idle.
Restricted time ONLY!!
