Hi there!
I’m trying very hard to learn Play Canvas and it’s going quite well. A couple of times I had to choose a learning method of reading the engine code and engine’s objects in console, but it was an interesting journey!
Anyway, this time I don’t really know what to do - either I’m doing something wrong here or the engine and hopefully you’ll help me :).
So, basically I have a game with procedurally generated world and when I’m walking around long enough, what I’m getting is:
Cannot enlarge memory arrays. Either (1) compile with -s TOTAL_MEMORY=X with X higher than the current value 67108864, (2) compile with -s ALLOW_MEMORY_GROWTH=1 which adjusts the size at runtime but prevents some optimizations, (3) set Module.TOTAL_MEMORY to a higher value before the program runs, or if you want malloc to return NULL (0) instead of this abort, compile with -s ABORTING_MALLOC=0
That’s strange, as the profiler shows quite stable VRAM statistics all the time:
I’ve put dozens of console.logs() to find out precisely, what line of code is causing the memory enlargement. I checked all the lists and dictionaries I have and I’m almost sure that’s none of them. As it turned out, logs showed the error is raised during the mesh creation process. More precise, collision mesh assignment:
createMesh( data : MeshGenerationData ) {
let model = new pc.Model();
let pn = new pc.GraphNode();
model.graph = pn;
for ( let i = 0; i < data.triangles.count; i++ ) { // data.triangles.count=1 (those are subarrays of triangles)
model.meshInstances.push( this.createMeshInstance( data, i, pn ) );
}
this.entity.addComponent("model", {
type: 'asset'
});
this.entity.model.model = model;
this.entity.model.castShadows = false;
this.entity.addComponent("collision", {
type: 'mesh'
});
let pn2 = new pc.GraphNode();
let collisionModel = new pc.Model();
collisionModel.graph = pn2;
collisionModel.meshInstances.push( this.createColliderMeshInstance( data, pn2 ) );
console.log( this.entity );
this.entity.collision.model = collisionModel;
console.log( "/\ Error happens here!" );
this.entity.addComponent('rigidbody', {
friction: 0.5,
type: 'static'
});
}
Aside this code, the only related thing I’m doing is destroying the same entity later:
delEntity( ch : ChunkInfo ) {
if ( ch.entity ) {
if ( ch.entity.model && ch.entity.model.model ) {
ch.entity.model.model.destroy();
}
if ( ch.entity.collision && ch.entity.collision.model ) {
ch.entity.collision.model.destroy();
}
ch.entity.destroy();
ch.entity = null;
}
}
There’s no other code “touching” those entities - no adding components, removing them etc etc. So I assume the problem is somewhere within this code…
Maybe anyone of you had a similar problem before?
