\nTo play our heel-toe components in UE4, we will trigger them separately, and control the offset in the game engine. However, to test the heel-toe components as one footstep in Atom Craft, we can create a temporary Cue and manually offset them in the Timeline. <\/p>\n
\n[Note] To avoid clutter in our UE4 project, we can place the heel-toe components in a Private Cue Folder.\n<\/p>\n
UE4 <\/h2>\n
\nTo implement our audio, we can use the Third Person Blueprints template that UE4 provides. As usual, the documentation is the best place to start if you need help getting the CRIWARE SDK integrated, and the CueSheet Binary imported.<\/p>\n
\nTo determine what surface our character is walking on, we can make use of UE4\u2019s Physics Material<\/b> feature. To set this up, we first need to select Edit \u2192 Project Settings \u2192 Engine \u2192 Physics and scroll to the bottom.\n<\/p>\n

<\/p>\n
\nUnder Physical Surface, we can create surface types for each the Selector Labels we defined in Atom Craft: \u201cGravel,\u201d \u201cMetal,\u201d and \u201cWood.\u201d Next, in the Content Browser, right-click, and select Physics \u2192 Physics Material. Then, create a new Physics Material<\/b> for each of the above Physical Surfaces, and name them accordingly.<\/p>\n
![\"3\"](\"https:\/\/blog.criware.com\/wp-content\/uploads\/2020\/08\/3.png\")
<\/p>\n
\nOpen each Physics Material<\/b> and under Physical Properties, set the Surface Type to match to the Physical Surface created in the Project Settings menu.<\/p>\n

<\/p>\n
\nNext, we can create some Planes to test each of our surfaces. To assign our Physics Materials, we can drag from the Content Browser onto Phy Material Override under the Collision heading in the details panel while the appropriate Actor is selected.<\/p>\n

<\/p>\n
\nWe can control the heel-toe playback via different methods. One of the simplest is to scrub through the Timeline of our walking Animation manually, and right-click on the Notifies timeline \u2192 Add Notify \u2192 PlayAtomCue when the heel lands, then again when the toes land. Let\u2019s go ahead and do this for both the ThirdPersonRun and ThirdPersonWalk animations, which can be found under Content \u2192 Mannequin \u2192 Animations. A Blend Space<\/b> controls the transition between idle, walking, and running states. If sounds are triggering erroneously, ensure that Notify Trigger Mode is set to \u201cHighest Weighted Animation\u201d in the Asset Details panel on the Blend Space<\/b> asset.\n<\/p>\n
![\"6\"](\"https:\/\/blog.criware.com\/wp-content\/uploads\/2020\/08\/6.png\")
<\/p>\n
\nWe also need to ensure the correct sound plays for each. To do this, we need to highlight each Anim Notify and select the right sound from the dropdown in the Details panel.\n<\/p>\n

<\/p>\n
\nPlaying the game now should subtly reflect the difference in movement speed. However, we need one last piece of code to control the playback relative to surface type. Let\u2019s open the ThirdPersonCharacter Blueprint and navigate to the \u201cMovement input\u201d section of the Blueprint. To check the surface below the character, we can do a simple LineTraceByChannel directly down from the character.<\/p>\n
![\"8\"](\"https:\/\/blog.criware.com\/wp-content\/uploads\/2020\/08\/8.png\")
<\/p>\n
\nThe above code is run just after adding the player\u2019s input to the character\u2019s Add Movement Input. This code will GetActorLocation from the character (self) to determine the Start point and calculate a line straight down to get the End point.\n<\/p>\n
![\"9\"](\"https:\/\/blog.criware.com\/wp-content\/uploads\/2020\/08\/9.png\")
<\/p>\n
\nWe can finally Get Surface Type from the Out Hit of the line trace and use Select to output the correct String based on what was hit. Since we named our Physical Surfaces in UE4 the same as our Selector Labels in Atom Craft, we can type strings that match the inputs. We can also determine what sound should play if a surface doesn\u2019t have a Physics Material attached by setting a Selector Label for the Default input.<\/p>\n","protected":false},"excerpt":{"rendered":"
